A mock interview is a simulated job interview that allows an individual to practice their interview skills in a safe and controlled environment. It typically involves role-playing with another person acting as the interviewer, while the candidate plays themselves. The purpose of a mock interview is to help prepare candidates for real job interviews by giving them an opportunity to rehearse common interview questions and scenarios, improve their communication skills, build confidence, and receive feedback on their performance. Mock interviews are often conducted by career counselors, human resources professionals or experienced interviewers, and can be a valuable tool in helping candidates succeed in their job search.
