Project Retro Interview Format

The project retrospective interview format can vary by company, but it generally follows a structured approach to evaluate your past project experiences. At a high level, it can be classified with 2 formats:

• Heavy format - 1-hour long, one-pager write-up prior to interview
• Light format - 40-minute long, usually just present your slides during the interview
