Employers use various assessment techniques such as asking specific questions related to the job position being offered, giving written tests simulating real-life scenarios targeted at evaluating one’s comprehension and ability to apply concepts to actual situations, conducting skills demonstrations through role-playing, case studies, etc., observing body language & non-verbal cues during conversations – all these help assess an individual’s level of expertise for a given role in question while determining whether he/she has sufficient depth/competence required to succeed therein.
