I was contacted via a recruiter who found me on LinkedIn. I interviewed for a specialized Product Manager role in the Menlo Park office, but since I do not live on the West Coast my interviews were all via videoconference and phone. I had 1 screening call with the recruiter, then 3 videoconference interviews: 1 with the hiring manager, 1 product execution interview (2 questions), and 1 product sense interview (2 questions). The interviews were generally pleasant and moved fast (all 45 min each except for the 30 min initial screen). I advanced between each of the 3 videoconference rounds and was given the notification of the advancement by my recruiter in between each -- it usually took 1 week to set up each subsequent interview. The screening with the recruiter was a review of my background and the position. The interview with the hiring manager was a deeper review of my background, then questions about my strengths and weaknesses as a product lead. Then we spoke about the team I would be joining and the role itself. Next was the product execution interview. I especially enjoyed the product execution interview because the interviewer was someone known in the tech space and a very strong interviewer -- he was very helpful in guiding the discussion, and I left thinking that he was someone I would absolutely love to work with. The questions he asked were centered around prioritizing how users are presented with modules and products on the FB app (particularly People You May Know vs an ad, and a new local search product). Next was the product sense interview. My final interviewer was weaker as an interviewer -- he did not provide as much guidance during the discussion and seemed more junior than my previous interviewers. He first asked me to pick a product I want to work on at FB and what I would do to improve it. Then, he asked an off-the-cuff question about my current industry during the product sense interview, which I believe to be was what led me not to move forward in the hiring process -- I made the big mistake of taking the question literally and went down the wrong path of providing a high level business strategy from the point of view of the business rather than a product strategy from the point of view of the user. After this interview my recruiter infomed me that they would not move forward. I was disappointed after getting this far into the interview process to have it end at this point-- I believe I could have advanced to the final round (it was my next step in the process), but it was definitely my mistake for not keeping the scope of my answer from a product standpoint in my last interview.
