A mock interview is a practice interview that allows job seekers to prepare for an actual interview by simulating the experience. It provides feedback to help candidates improve their communication skills, confidence, and ability to answer potential questions. Candidates should research the company, prepare answers for common questions, and have questions prepared. Mock interviews help practice responding to questions like "tell me about yourself" or industry-specific questions. For one mock interview, a candidate researched the BBC and pitched a new TV program idea based on a book to receive feedback on their presentation skills and ability to answer follow up questions about their proposal.
