Background
The field of human resources has transformed traditional and outdated personnel selection methods through technological advancements, paving the way for more technologically advanced methods that reduce hiring costs and optimize the evaluation of candidates during the recruitment process. This is particularly relevant when it comes to millennials and Generation Z. Gamification is among these methods. It can be defined as "a package of services in which a basic service is enhanced by rule-based service systems that provide the user with feedback and interaction mechanisms that aim to facilitate and support users' global value creation" [1], and in recent years, it has become an increasingly popular trend in nongaming contexts [2] to increase motivation and engagement [3]. Gamification involves the use of structured rules and competitive conflicts to achieve specific goals, and in which a person is fully engaged with the context, losing track of time and experiencing the thrill of doing rather than achieving external rewards [4]. Research has shown that play and games can be linked to positive social behavior [5], the development of important skills such as self-regulation and empathy [6], and the promotion of teamwork [7].
Gamification is often used to enhance services and test gaming experiences and can be a powerful tool for influencing behavior [1]. However, some studies have examined issues related to gamification [8]. This technique is applied in settings related to learning, business, or promoting a product or service [9]. Through elements, such as competition, goal achievement, and reward, gamification can increase users' motivation, engagement, and satisfaction in an activity [10,11].
Many researchers have suggested that gamification and game-based assessments could predict work performance as an alternative to traditional selection methods [12,13]. Fetzer et al [13], according to the concept of "stealth assessment," highlighted the potential of game-based assessments for predicting work performance. Invisible evaluation can accurately and efficiently detect a subject's level of competence, can continuously extract data on their performance during the game [14], and is almost undetectable, reducing test anxiety while maintaining validity and reliability [15]. In this context, a gamified assessment environment could distract candidates from being assessed, promoting unconscious rather than desirable or socially acceptable behavior. Assessment and learning tools that may be created through the use of gamification are known as serious games [16], which are games designed for a primary purpose other than pure entertainment [17], like supporting human capital development [18]. Serious games are designed for educational, training, or informational purposes that combine the playful experience with learning specific skills and competencies [19]. Unlike traditional games, serious games were created to impart knowledge and teach players how to apply those skills in real life by creating engaging and entertaining experiences that prompt users to perform certain actions, improving the effectiveness and efficiency of those activities.
Various sectors, such as education [20], health care [21], mobility [22], marketing [23], and the environment [24], have been equipped with this innovation, simulating situations in which the player must make decisions, solve problems, or develop specific skills. Moreover, owing to the interactive nature of serious games, players can learn actively, receiving immediate feedback on their progress and the correctness of their actions [25].
If the game is user-friendly and realistic, it tends to generate positive responses from candidates [26]. Thus, one of the cornerstones of these games (as well as an aspect this paper will focus on) is the development of awareness related to one's skills, particularly those skills called "soft skills," which are indispensable in the world of work [27].
In relation to the connection between gamification and transversal skills, game elements, such as textures, feedback, avatars, visual effects, and voiceovers, can be effectively used to assess candidates' soft skills [28].
Problem-solving skills, strategic thinking, and adaptation to new contexts are soft skills, also known as "behavioral skills." They are non-technical skills (as opposed to hard skills) important for personal and professional success. Using game mechanics, gamification can make learning these skills more engaging and effective. Serious games play a key role in developing soft skills (such as problem solving, planning, and analytical thinking) in the world of work [27]. Certain elements, such as a risk-free environment, predispose users to a setting conducive to experimentation and exploration, activating stimuli, such as curiosity, learning by discovery, and perseverance [29].
Serious games are playful and interactive tools often used in education with pedagogical goals, which are designed to teach skills, notions, and strategies [30,31]. Serious games offer active involvement, immediate feedback, experiential learning, collaborative learning, and learning personalization, which enhance positive learning effects [32]. The scenarios designed for serious games have a positive relationship with student engagement and academic performance [33]. Despite their potential, serious games still pose a challenge to the educational world, and there is a need for more emphasis on less formal and traditional models that are suitable for teaching today's generation of students [34]. Serious games are an important resource for the world of training and education, facilitating the learning of specific disciplines.
Transversal skills often overlap with digital skills, which have become increasingly necessary for performing tasks due to the growth of technology in recent years. Digital skills involve the use of information and communications technology (ICT) tools and can be classified as operational, formal, informational, or strategic skills [35].
Based on these premises, this research proposes an innovative method for addressing an issue dear to companies, the recruitment process. Recruiting an unsuitable candidate can be very costly, both in terms of money and nonproductive time. Therefore, many companies are looking for innovative ways to improve their recruitment process to attract and identify the most suitable candidates for available positions. This involves the use of cutting-edge recruiting techniques and an increased focus on assessing candidates' skills and qualities [36].
Psychological tests that measure cognitive abilities and personality tests, which are traditional selection methods, can somewhat predict job performance [37]. As previously mentioned, the game is an attractive and valid alternative to traditional selection methods, and gamifying these tests can be a way to assess candidates with the benefits stated above.
The COVID-19 pandemic has prompted a shift in the labor market toward Industry 5.0 to the New Normal Era, a time of collaboration between advanced technology and human creativity to address business, social, and environmental challenges [38]. This has had an impact on the labor market, affecting both demand and requirements, as well as leading to the emergence of the "great resignation" phenomenon, in which individuals across countries and industries are exhibiting a heightened awareness of work conditions and opportunities [39,40].
To successfully adopt artificial intelligence (AI), organizations and individuals must embrace transformative changes in their practices, recognizing the foundational role of connected technologies in driving increased digitization in business and management worldwide. Key factors for successful AI adoption include team coordination, organizational culture, governance strategy, and AI-employee integration strategies. Furthermore, the integration of serious games and AI provides new computational tools for social research. Soft skills, such as communication, problem solving, critical thinking, and creativity, are crucial for successful AI adoption, while leadership plays a vital role in setting a vision and strategy for its implementation [41,42].
Recent studies have emphasized the importance of soft skills and talent in the New Normal Era, where work has changed significantly and new methodologies, such as smart working and remote working, are becoming increasingly prevalent. As a result, soft skills are now a top organizational priority [43].

Industry 5.0: Impact of Emerging Technologies on Gamification and the Labor Market
With the increasing adoption of new technologies, such as AI, virtual reality, metaverse, blockchain, augmented reality, and collaborative robots, it is crucial to understand the transition from Industry 4.0 to Industry 5.0 for creating sustainable business and management practices. Industry 4.0 was characterized by automation technologies, the Internet of Things, and smart factories, while Industry 5.0 involves the collaboration between advanced machinery and human creativity to solve business, social, and environmental issues. The adoption of transformative changes in practices is essential for organizations and individuals to understand as these connected technologies provide the foundation for increased digitization in business and management worldwide. While the use of serious games and gamification has become increasingly popular in recent years, some of these emerging technologies, particularly AI, have the potential to be disruptive for the world of work and have a significant impact on human resources, recruitment, and corporate life [38].
Team coordination and organizational culture are also crucial elements that organizations must consider when adopting AI. Effective coordination between team members is essential for successful AI implementation, and organizational culture plays a critical role in supporting this coordination. An innovation mindset is also necessary to foster a culture of experimentation, learning, and continuous improvement, which are all essential for successful AI adoption.
Governance strategy is another key area that organizations must consider when adopting AI. Effective governance ensures that AI is being used ethically, responsibly, and in compliance with legal and regulatory frameworks. AI-employee integration strategies are also important, as they help to ensure that employees feel comfortable working with AI systems and are equipped with the necessary skills to do so [41].
Pérez et al [42] suggested that the integration of serious games and AI offers new computational tools for social research. By developing and applying gamification with an eye toward both design and efficacy, organizations can increase productivity and promote better decision-making processes in the workplace. The use of gamification and serious games in the workplace can be a promising tool to enhance motivation, engagement, and decision-making processes among employees.
An evidence-based approach to gamification considers its effectiveness to be dependent on the use of scientifically proven principles and tactics that can impact outcomes [44]. Optimistic results have been found in the integration of some of the newest technologies, as AI, virtual reality, and serious games are being increasingly used in several industries, such as the healthcare industry where there was a great effort concerning new technologies and research during the COVID-19 pandemic, yielding favorable outcomes for the treatment of various health conditions as well as for medical education and training [45][46][47]. Moreover, Schönbohm and Zhang [48] revealed the effectiveness of serious games in facilitating strategic decision-making in the context of the COVID-19 pandemic.
In the era of the new normal, the global workforce is experiencing an unprecedented phenomenon known as the "great resignation." This phenomenon is characterized by individuals in various countries and industries exhibiting a heightened awareness of work conditions and opportunities, which is indicative of an overall increase in people's awareness of work. However, this phenomenon has also brought about uncertainty, challenges, and opportunities for organizations due to external factors such as the gig economy and the implementation of technology [39,40].
Recent research by Duch-Brown et al [49] investigated the relationship between market power, AI, and online labor markets. They showed that market-designing platform providers can influence labor demand and supply elasticities on online labor markets by setting specific terms and conditions on the platform. The study also revealed a significantly higher demand for AI-related labor and a significantly lower supply of AI-related labor, indicating the need for further exploration of the role of AI in online labor markets. Similarly, Deranty and Corbin [50] highlighted the potential societal impacts of AI deployment in work, particularly in the areas of technological unemployment and wealth polarization.
This presents new challenges and opportunities for soft skills [51], as well as technical skills and fusion skills [52], which are those skills and attributes required for individuals to thrive in the fusion environment of the 21st century. Therefore, staying updated with technological advancements and market-specific demands is essential for individuals employed in data science-related fields (more so than others) to enhance and maintain their employability, especially in the digital renaissance. Additionally, real-time identification of market demands plays a crucial role in balancing the adequate supply and demand of talent in this era [53].

The Future of Work Relies on Soft Skills in the New Normal Era
A new technological revolution is going on, and many organizations are eager to adopt new technologies in order to gain a competitive advantage. However, implementing new tools, like AI-based tools and technologies, is not enough to achieve success. A recent review on human resource management conducted in March 2023 revealed that organizations need to look beyond technical resources and focus on developing nontechnical resources as well [41]. The review highlights several nontechnical resources that are critical to successful AI adoption. These include human skills and competencies, such as communication, problem solving, critical thinking, and creativity, which are essential for effective collaboration with AI systems. Additionally, leadership is vital for setting a vision and strategy for AI adoption and ensuring that it aligns with the organization's overall goals and values. In conclusion, the review underscores the importance of developing nontechnical resources in addition to technical resources when adopting AI. By investing in human skills and competencies, leadership, team coordination, organizational culture, innovation mindset, governance strategies, and AI-employee integration strategies, organizations can fully realize the benefits of AI adoption and gain a competitive advantage in the marketplace [41].
The 2023 Pulse of the Profession report by Project Management Institute highlights that power skills, which are soft skills built upon a solid foundation of technical skills, are a top organizational priority [43]. Developing these skills can lead to delivering results that add value to both the organization and its customers.
Redefining work requires more than skill development, as skills have inherent limitations. Simply retraining workers to perform different routine tasks or adapting to new technologies to complete the same tasks does not address the underlying challenges for workers or capture the potential benefits for companies. The vision of redefined work involves shifting workers' focus from routine tasks to identifying and resolving hidden issues and opportunities. While automation can facilitate this shift, it is not just about automating tasks or using technology. It does not involve changing the workforce composition or retraining employees for different domains, and it does not require employee suggestion boxes, 20% work time for innovation or entrepreneurship, or innovation centers. Workers must develop and use their human abilities to identify issues, solve problems, implement solutions, and iterate to recognize and resolve hidden issues and opportunities. A key characteristic of this work vision is its continuous evolution. Problem identification and solution methods are typically used to correct processes, address deviations, or eliminate inefficiencies, with the goal of incorporating feedback into more structured and defined work. Loosening the structure is only a temporary measure to advance the process [51].
The job market has undergone a significant transformation due to the pandemic, which has been expedited by the emergence of new technologies. To thrive in this new era, possessing soft skills, such as communication, problem solving, creativity, and collaboration, as well as the ability to adapt to change, is crucial [54], even if digital and technological skills are vital for enhancing a firm's performance. Moreover, Akrim [55] stressed that while knowledge is important, soft skills cannot be overstated when it comes to securing one's future.
To gain a competitive edge in the job market, integrating talent and knowledge management strategies is imperative [56], and to succeed in the future of work, prioritizing soft skills and talent management strategies in recruitment and training processes is essential. Identifying unique talents and skills is crucial to gaining a competitive advantage. High demand for soft skills, such as creativity, emotional intelligence, critical thinking, and problem solving, necessitates their recognition and prioritization in organizations' development efforts [57].

The Pedagogical Side of Serious Games
Serious games serve as an effective and result-oriented medium, utilizing interactive and playful forms of engagement [30]. They represent tools designed with the goal of teaching something, such as skills, notions, and strategies, and offer the possibility for the user to identify with learning and formative situations, and thus, it can be said that they pose pedagogical goals [31]. Serious games are associated with multiple advantages from pedagogical and formative points of view, including active involvement, as the player becomes the protagonist of learning and is stimulated to explore, experiment, and reason independently [29]. Another advantage is immediate feedback, as they provide a timely and accurate response on the player's actions, allowing learning based on error and its correction. Other advantages include experiential learning related to scientific literacy [58], as they allow for real-world situations to be experienced and simulated, providing a direct and engaging educational experience; collaborative learning, as they can be used to foster cooperative learning, stimulating participation and information sharing even in educational settings between teachers and students [59,60]; and learning personalization [61], as they can be designed to adapt to each player's cognitive needs and abilities, sparking and maintaining player interest and motivation and enhancing positive learning effects [32]. In addition, there is a positive relationship between the scenarios designed for serious games and the expected outcomes of the learning experience [62] considering, as part of this process, student engagement and academic performance [33].
Despite the potential of these tools, they still pose a challenge to the educational world [34]. It is important to place more emphasis on less formal and traditional models that are more suitable for teaching, which can be projected to the generation of students experiencing school today. Serious games, according to this perspective, represent an important resource for the world of training and education, and are facilitators for learning specific disciplines.

Soft Skills in the Labor World
Soft skills refer to a range of personal attributes, social abilities, and communication competencies that are necessary for success in the workplace. These skills, which are distinct from technical skills, include qualities such as positive attitudes, good communication, and strong interpersonal skills. They are also described as the "human skills" or "people skills" needed to effectively use technical knowledge and expertise in a professional setting [63].
Several studies have focused on identifying the key soft skills that are valuable in the labor market [64]. Several international studies have shown that soft skills are critical to our future success, and their importance is recognized by education providers, academics, human resource departments, and businesses [65][66][67][68].
This research aims to understand how companies and economic organizations that recruit, hire, and develop professionals at a medium to high-level view and value soft skills in their human resource development process [69].
According to the study, the most important soft skills for different groups, determined based on criteria such as significance, relevance, availability in the job market, and negative impact if lacking, are as follows: problem solving (for the group focused on achieving results), team working (for the group focused on mastering social skills), and time management (for the group focused on making progress in the workforce).
In order to examine the testability and relevance of certain soft skills, it is also useful to analyze communication and decision-making in greater depth. Additionally, problem solving may be linked to self-directed learning and communication for goal orientation, and both of these skills may be considered when discussing digital skills [70]. Therefore, it is advisable to carefully analyze these 5 skills, which were identified through a classic assessment. To assess communication [71], the communicative style (aggressive, passive, or assertive) [72][73][74] was adopted, and for problem solving, models, such as DMAIC (Define, Measure, Analyze, Improve, and Control) [75] and Problem Solving Inventory (PSI) [76], were used. Team working and related skills developed in group environments are highly sought after by recruiters when hiring [77]. The research was inspired by the Comprehensive Assessment of Team Member Effectiveness (CATME) [78], and for decision-making, the cognitive style (a person's preferred way of thinking and tendency to adopt certain strategies more frequently) [79] was evaluated using the General Decision-Making Styles (GDMS) scale [80]. Time management, as theorized by Lakein [81] and others, was assessed using the time management behavior scale [82]. Soft skills are increasingly recognized as critical to future success and are valued by those in education, academia, and human resource departments. They also help organizations gain new customers, increase revenue, and reduce employee turnover, which is why employers are placing an increasing emphasis on these skills [66].

Purpose of the Study and Origins
This study was conceived within the scope of the SWAG (Skills in Work-life Analysis Game) project. SWAG sets out to democratize the human resource world, through the use of intergenerational language, and it is inclusive and comprehensive of the needs, complexity, and peculiarities of today's and tomorrow's talents, connecting the right person to the right position. The SWAG team (involving Altomari Luca, Altomari Natalia, and Vigliaturo Daniele) was created in the context of the first cycle of "UniCaLab" (Contamination Lab of the University of Calabria) in 2019 (path concluded among the 3 winners) and achieved victory in Invitalia's "#IoRestoAlSudHackathonTour*" contest in the same year.
In this work, a new assessment framework is presented that takes into account the needs of the labor market and is based on gamification, with a focus on the concept of "recrutainment" (a term combining "recruitment" and "entertainment"), which integrates cognitive and aptitude assessment methods into the personnel selection process [83] and is not only partially conceived as a subset of gamification, but also goes beyond it [84]. In this study, a serious game that assesses the most in-demand skills in the job market and provides feedback is illustrated, proposing a set of guidelines for the development of serious games while describing the game design process. The first trial of the game was conducted and positive results were achieved, paving the way for further studies.
The serious game Among the Office Criticality (AOC) was developed by the SWAG team as a desktop version with the technical support of Artémat.

Research Methodology and Proposal of a Serious Game
The purpose of this study was to develop a model that can identify and evaluate certain work-life skills (in this case, 5 soft skills that are in high demand in the job market) and provide feedback to the user who uses the tool. Gamification is particularly suitable for this purpose because it allows for the creation of tools that can provide quick, objective, and standardized assessments [85] after an initial design and implementation effort, while also allowing for a more informal approach to the person being evaluated [12,13]. The study presents the AOC serious game, which is able to detect the 5 soft skills mentioned above. The AOC serious game uses a set of sequence analysis techniques, which is known as process mining, to overcome the limitations of traditional skills assessment methods [85]. The user interacts with the game, which tracks key performance indicators (KPIs) based on the user's choices at each decision point and saves them in an event log at the end of the game. These events and values are processed by process mining software, which generates an output (Figure 1) [85]. The software that analyzes the event log uses an algorithm to read the data in the log and create a model. This model is then used to apply the metrics of the specific evaluation tool to produce the final report.
AOC is a serious game that is structured as a tree graph, with decisional moments represented as nodes. Analyzing the user's choices within the game involves identifying the pattern arcs that connect the nodes. However, analyzing all user actions within the game can cause scalability issues. To address this, the event log only records data related to decisional moments and the duration of the game, rather than all interactions. In this case, sequence analysis can be helpful in solving or mitigating the problem [85]. In the AOC game, metrics are based on a data set of fixed-length numerical vectors and an overall rating formula. These vectors are added together based on the entries in the event log to create a final vector, the values of which are then used in the formula to produce a numerical result. This result, as well as the individual values, can be easily translated into a final report that is provided to the user in both graphical and narrative forms. The design of serious game processes can be performed in 2 steps: context analysis and iterative concept use. The first step involves using user-centered design methods, which focus on the user's intent, situation, activity, and characteristics. The second step involves testing the tool, once it has been defined and materialized as a prototype or mock-up, in order to improve it with a focus on attractiveness, motivation, and support for activities [86]. It is important to keep in mind some fundamental principles of gamification, such as freedom of choice, benefits and relevance, personalized experience, long-term interaction, unwanted side events, and ethical and legal elements [86]. The tree graph structure containing the decisions should also be considered.

AOC Serious Game
AOC is a serious game that assesses 5 soft skills by immersing users in a simulated game context where they can use various tools as needed. The game context places the player directly into a company through a specific delivery at the beginning of the game. In the simulation, the player, who is starting their work experience, begins their journey at a fictious firm with an apprenticeship contract. At the start of the simulation, the user is presented with an organizational chart, and graphic and textual descriptions of the business context. Over the first 6 months of the game, the player must interact with other characters to complete tasks, deal with unexpected events, and make decisions, choosing the means of communication and working with superiors and other team members in order to achieve the best possible result at the end of the simulation. At the end of the game, based on the choices made, the user is presented with a scenario that reflects the path they took. The contract can be converted into permanent employment, extended for an additional 6 months, or terminated.

Serious Game Output
In the alpha version of the game, the user is presented with a series of decisions that are related to values for various soft skills. These values are individual variables that are combined into a resultant vector, denoted as R. The R values are then input into the overall evaluation formula, which produces a numerical result, designated as x. This result corresponds to an outcome that is related to the objective of the game. As the user makes decisions, the events of the game progress according to the graph. Each event occurs consecutively and presents the user with contextual choices that are as visual and immediate as possible (eg, a choice between 3 interactive texts). The values assigned to each decision are based on data from previous studies and the literature used to construct the game [87]. The game has a maximum duration of 30 minutes, after which the available time (displayed as a countdown) reaches zero. If the simulation is not completed at this point, the final result is the R vector, which does not consider any subsequent decisional moments and includes a penalty for time management. The "first-person" perspective is intentionally designed to increase the user's engagement and encourage active interaction.
In 2017, van Laar et al [88] conducted a study that examined 75 studies on 21st century skills and found that problem solving and communication were the most commonly mentioned skills, with 24 and 22 quotes, respectively. In this study, communication was defined as the ability to transmit information effectively, while problem solving was defined as the ability to use ICT to understand and process problems and actively use knowledge to find solutions.
The structure of the graph, the assignment of scores, and the analysis of these scores are all built using techniques from the Theory of Graphs, in line with theory and market research that emphasizes the importance of problem solving, which is tested in greater detail than the other skills. This is evident in the analysis of paths that maximize and minimize the variables associated with the skills, which has shown a range of 33 possible values for problem solving. The skills of team working, time management, and decision-making have 21 possible values and make up a total of 48% of the testing (Figure 2). The remaining 52% is composed of problem solving and communication, with this last skill requiring more attention as it is divided into 3 categories: passive communicative style, aggressive communicative style, and assertive communicative style. Variables used to identify the communicative style are also included in this percentage. The slight differences in amplitude within the ranges can be attributed to both psychobehavioral factors and mathematical advantages. The psychobehavioral reason is that each communication style has the potential to generate unexpected events within interpersonal relationships (ordered: aggressive, passive, and assertive). The mathematical advantage is that the 3 variables can never be equal in any of the possible combinations. The outcome for the user consists of a final report that includes both graphical and narrative components ( Table  1).The graphical component consists of a 2D diagram that incorporates a polygon, with each vertex representing the user's scaled final scores in the four soft skills: team working, time management, decision-making, and problem solving. This polygon describes a surface of amplitude that is directly proportional to the x value resulting from the overall evaluation formula. The textual component includes a result relating to the final goal (3 possible scenarios) and different sections describing the user's score in each individual skill (low, medium, and high). In the graphical component, the dominant communication style is also explicitly highlighted (aggressive, passive, or assertive).

Ethics Approval
Ethics approval for the research project, "Innovation in Teaching Methods" was granted by the Ethics Committee of the University of Calabria (COMITATO ETICO DI ATENEO -CEA) on May 9, 2019. The project, which was conducted within the University of Calabria, aimed to assess soft skills using the tool developed by SWAG, alongside human tutors. Adhering to the approved ethical guidelines, the research team ensured participant confidentiality and privacy throughout the data analysis process.

Elaboration and Descriptive Statistical Analysis
To test the serious game, the researchers conducted a pilot study with 160 subjects from the University of Calabria (Italy) who were enrolled in the 2018/2019 academic year. Table 2 and Figure 3 show the results of the preliminary data screening and the normal curve of the collected data. According to the criteria of Curran, West, and Finch [89] (asymmetry greater than |1|=severe nonnormality; kurtosis greater than |3|=moderate nonnormality), the value for aggressive communication was close to being severely nonnormal in terms of asymmetry. This may be due to a small number of data points for individuals who had this type of communication as a result. While only 1 item showed these values, the results of the descriptive analyses can still be considered reliable.
Fidelity, referring to the consistency of the game with the real world, is a crucial attribute for reality-based games as it enhances player immersion. Immersion refers to the player's involvement in the "player's world," which is a crucial factor in motivating players to pursue "serious" goals [90]. However, it is important to balance immersion with entertainment elements, as previous studies have shown [27,91,92]. Fidelity can also contribute to the entertainment value of a game.
The enjoyment of playing a video game can increase motivation and lead players to find pleasure in the activities within the game, regardless of their achievements. This is especially relevant when the objectives of the game are perceived as enjoyable by the player [90].
Previous studies have found that user-perceived determinants after playing a serious game include feedback, ease of use and usability, and learning effectiveness, among others. This is consistent with the findings of this study, in which the analysis of the open-ended questionnaire taken by users at the end of the game revealed factors associated with the functionality cluster, such as ease of use and effectiveness [93]. Additionally, the enjoyment and presence-immersion factors identified in the study by Fokides et al [93] can be linked to the pleasure and involvement clusters.
According to a literature review (54 studies, 59 data sets, and 586 variables) conducted in 2019 by Baptista and Oliveira on gamification, the best predictors of acceptance for gamified technology were attitude, enjoyment, and usefulness on intention. The clusters of adjectives that were found to be most significant (involvement, pleasure, and functionality) in this study aligned with these findings, suggesting that the proposed serious game follows the trend of accepted gamification technology.
The results of the study showed that users were particularly interested in the level of engagement and interest generated by the simulation [94], as well as the entertainment value and overall emotional reactions (such as "interesting," "engaging," and "stimulating"). This aligns with the concept of recrutainment, which emphasizes the role of engagement in the recruitment process [95]. In addition, users were interested in the functionality of the assessment tool, as indicated by adjectives like "useful," "effective," and "efficient." These results highlight the importance of designing the tool with users' needs in mind. Overall, about half (193/392, 49.2%) of the adjectives in the involvement and pleasure clusters [86] supported the theory of user-centered design.

Role of Gamification in Assessing Soft Skills for Talent Acquisition
This study proposes an immersive serious game model, called AOC, which aims to evaluate 5 important soft skills sought after in the job market, namely, problem solving, team working, time management, decision-making, and communication. The design of AOC was based on the literature and followed a user-centered design approach to create a user-friendly and intuitive environment. The output provided to the user holds significance as AOC was designed to generate value for both the evaluator and the evaluated subject. Therefore, it is essential to show areas of potential growth and increase the user's self-awareness after the simulation. This study found that the proposed serious game model may be considered in line with existing literature. Nevertheless, it is worth acknowledging that this study is not without limitations. One such limitation is the relatively small sample size, which may have implications for the generalizability of the findings. To build upon and strengthen our findings, future studies with larger and more diverse samples are recommended.
Gamification is a viable solution to improve some aspects of personnel selection [95], particularly the concept of recrutainment, which focuses on the candidate's involvement in the selection process [4,83]. Serious games are useful for both education and assessment, and are increasingly used in business and work contexts, as they help reduce selection time, avoid subjective evaluation [70], and reduce cognitive bias. They also allow for employer branding, which can positively influence the user's opinion of the evaluator [84]. According to Diercks and Kupka [84], the use of self-assessment elements in selection can increase the success rate of achieving objectives to 93%, especially when employer branding and personnel marketing are properly carried out. The term "recrutainment," which combines the words "recruiting" and "entertainment," has gained popularity among Generation Y and refers to gamified, user-oriented, and simulation games that aim to improve the quality of suitable candidates through self-assessment procedures [84]. The use of gamification, combined with cognitive and aptitude assessment methods [57], is increasing in the field of recruitment and human resources in general. It is expected to triple from 2020 to 2025, with a focus on its use in personnel selection [95].
However, as noted by Kirovska et al in 2020 [95], implementing a gamification model in the recruitment process carries risks, including the need for constant monitoring. Therefore, many companies outsource it to third-party organizations to benefit from reduced hiring times and increased interaction levels, as well as to delegate risks. Attracting innovative talent is a goal for many organizations and allows them to consider characteristics and attitudes aligned with their brand's aim. Gamification also encourages the user to do more than what is required [96], which can be a competitive advantage. In 2017, Korn et al [83] identified 42 applications (evaluating 60% of them) proposed by well-known organizations that use recrutainment, with a focus on the correlation between the profile and the hiring subject's needs (job relatedness). They also emphasized that a low score in a single game does not necessarily mean poor user skills and that, in fact, each result could identify areas for improvement.
The human resource industry has come to fully understand and use gamification in the talent acquisition process, including from a strategic perspective. While the evaluation of technical skills is important and can be inferred from a candidate's resume, transversal skills, which are intrinsic, innate, or developed through training and life experiences, are more difficult to objectively evaluate. This requires a significant amount of time and energy from human resource professionals [97]. In this context, gamification becomes important as it allows certain characteristics to emerge indirectly, which can be very complicated to discover otherwise [63]. Soft skills can make a significant difference in the business environment, and serious games are particularly effective at evaluating them because they can be assessed in various contexts and methods [12,13], including through self-assessment.

Conclusions and Future Developments
This research presents AOC, a serious game designed to meet the needs of the job market and place the user at the center. Evaluation techniques consistent with the literature were used to create an interdisciplinary approach for adequately evaluating the user and adding value. Initial analysis suggested that the scores obtained by subjects during the serious game can be generalized to the general population. Additionally, feedback from a postgame questionnaire indicated that the game is engaging, enjoyable, functional, innovative, and realistic, and promotes personal growth. The feedback specifically emphasizes the engagement and interest sparked by the simulation, aligning with the principles of user-centered design and recrutainment theory.
In conclusion, we propose the methodologies used in the development of the serious game AOC as a framework for designing serious games that consider the key aspects of the user journey and their relevance to theory and traditional assessment.
Future work may include analyses of the data generated by the serious game, including skills of the studied sample, skill development over time, cross-analysis with other samples, and comparison with data from other serious games evaluating different work-life skills.
