      Director of Product Management Interview

      Oct 18, 2023
      Anonymous Interview Candidate
      No offer
      Negative experience
      Average interview

      Application

      I applied through a recruiter. The process took 2 weeks. I interviewed at BillionToOne

      Interview

      Ridiculous process, met with R&D before even meeting hiring manager. This individual knew nothing about marketing or product management and asked questions completely irrelevant to the role. I'm not surprised this role is still not filled yet, sadly with the way they are searching and interviewing they will not get the right candidate.

      Interview questions [1]

      Question 1

      Drunk drivers: 1% of all drivers Out of every 100 random drivers you pull over, how many test positive (drunk)? Actually drunk: 1 - always test positive Not drunk: 99 - 9.9 test positive

      Difficult interview

      Application

      I applied through other source. The process took 3 weeks. I interviewed at BillionToOne (San Francisco, CA) in Dec 2024

      Interview

      Recruiter screen first and after passing, was followed by a scheduled r&d/stats interview and product sense interview Screen was personality fit/ resume overview, followed by more rigorous technical interview (45 min and 60 min)
