The interview process for a Product Manager at Mercari is thorough and designed to test both your high-level product vision and your execution capabilities. The process typically moves from initial screening to practical assessment, followed by deep-dive behavioral and strategic interviews.

Initially, you will connect with the Talent Acquisition team to align on basic qualifications, role expectations, and timezone availability. This is followed by a brief, casual conversation with a hiring manager to assess your high-level fit and interest in the company.

Following the initial conversations, the process moves into a practical assessment phase. This often involves a product case study or, for highly technical teams, a technical/development task.
