Assessing candidate’s personality as part of the selection process has long been controversial among practitioners and candidates alike. However, understanding personality, in particular how personality interacts with work-related situations resulting in behaviour, can be beneficial knowledge for hiring organisations to possess. Familiar methods of personality assessment which include simply administering personality tests to candidate’s have been criticised for their lack of measuring anything actually related to the job role¹ ². This creates an opening for the development of improved methods for assessing a candidate’s personality with inclusion of how their personality directly interacts with the job role at hand and how this might relate to their future performance in the role.
Why is it important to consider personality in recruitment?
Being able to gain some understanding of how a candidate might perform in the role being recruited for, as well as how the candidate will fit with the workplace as a whole is crucially important³. The importance of the selection process should not be overlooked by employers. It is estimated that a poor hiring decision could cost the employer 30% of that employee’s first year’s earnings⁴. There is research which suggests that assessing a candidate’s personality can help to provide employers with useful information regarding a candidate’s fit with the job role. The Big Five personality traits (agreeableness, conscientiousness, extraversion, neuroticism, and openness to experience) have been found to be able to, in part, predict future job performance⁵. For example, conscientiousness is related to a strong willingness to stick to workplace rules and make efforts in task completion⁵, and extraverts (characterised by being particularly outgoing and sociable) show more positive emotions and better performance in their role when that role requires them to express these behavioural characteristics⁶ ⁷.
New areas of personality-recruitment research
More recently, some researchers have begun to consider personality in terms of how traits are expressed in response to situational cues in the workplace⁸. Interest lies in how interactions between personality traits and situational cues result in variation in the behavioural expressions of personality traits, and how this relates to job performance. This is referred to as within-person variability, which simply describes the changes in people’s behaviours. Situational judgement tests (SJT’s) are a useful way of investigating how personality traits and situations interact⁹. SJT’s present candidates with a work-related situation and a series of responses to choose from that indicate which course of action they would most likely take. Combining SJT’s with personality allow the candidate’s chosen response to be linked with their underlying traits⁹.
Showing variation in behaviours is representative of a knowledge of how effective certain behaviours are for certain work-related situations. Being able to vary the expression of work-related behaviours depending on the situation has been shown to be related to higher supervisor ratings of job performance⁹. This is said to be because those who are able to show variability in their behaviours are better at adapting to varying situations by changing their behaviour to fit the situation¹⁰. This is useful for employers to be aware of as being able to adapt behaviour to fit with various work-related situations has obvious benefits for a number of multi-faceted roles.
The most recent study
A more recent study investigated variability in the Big Five personality traits in response to work-related situations using SJT’s, and how this was related to supervisor ratings of job performance. Data was collected from 92 employees working in the hospitality industry via an online survey. The survey included a personality assessment of the Big Five, and a series of SJT’s that presented situations that were both relevant to one of the Big Five traits (for example, a situation targeting extraversion that required sociability) and relevant to hospitality work. Each SJT required participants to choose from a series of responses that were either effective or ineffective for the situation, and relevant to the personality trait being targeted (for example, describing high or low levels of sociability). Participants were asked to select a response option that they would most likely do and one that they would least likely do. Employee’s supervisors were then asked to rate the employee’s job performance. Supervisor ratings were collected for 37 of the 92 employees.
The study aimed to explore within-person variability in the Big Five by assessing whether the employee’s natural personality traits effected their ability to vary their expression of each trait, as measured using the response options on the SJT. The study also aimed to explore whether showing variability was positively associated with supervisor ratings of job performance. The study found some evidence of within-person variability, finding, for example, that 40% of participants who scored low on agreeableness in the personality assessment were able to vary their natural trait level by selecting a response option that showed high levels of agreeableness because this was the most effective response to the situation. Whilst this study found a negative relationship between this variability and job performance, suggesting that showing variability was associated with lower ratings of job performance, this finding should be considered cautiously due to limited data. The overwhelming body of research suggests that variability is in fact positively related to job performance⁹ ¹¹.
What should be taken from this area of research?
These findings promote an opportunity to improve upon traditional methods of assessing candidate’s personality for use in workplace recruitment processes. Incorporating personality assessment with SJT’s allows employers to assess, and therefore better understand, how a candidate’s personality traits interact with key situational aspects of the job role. This approach would result in a selection method that is both job-related and provides an understanding of a candidate’s fundamental characteristics that could be used alone or to compliment other selection methods, such as traditional SJT’s. Such a hybrid method would provide an indication of how situational aspects of the job role interact with the candidate’s personality, resulting in job-related behaviours and performance. This method would also provide the opportunity to understand how dynamically candidates are able to respond to situational features of the role in terms of how they are able to vary their behavioural expressions to respond in the most effective way.
