Mock interviews can be videotaped; the candidate can view the tape afterward, and get feedback. There are coaches who can provide feedback on aspects of the interview process. Mock interviews are most common for job interviews, but may also be used to train public figures to handle interrogations by journalists, as well as help candidates for office prepare for debates.
Mock interviews provide a chance for candidates to record their interactions and review them later, receiving guidance from coaches on areas of improvement. This practice is commonly used in job hunting, but can also be applied to training public figures to handle questioning by journalists, as well as helping aspiring politicians prepare for debates.
