A recruiter reached out to me about a position I wasn't aware of. She was very nice, we spoke about the job and she scheduled a 45 min with the hiring manager. She was quick to respond and very professional. The hiring manager however was unpleasant, mentioned how stressed and burnt out several times during the interview in various ways and clearly did not think through the prompt he gave me. Plus he was clearly not in a good mood. He presented a case study that continued to change as I answered it. First he started with - you're working at Facebook and there's a decrease in friend requests. What do you do? In a PM interview you never want to jump to the conclusion that it's a technical bug/issue so I explored different avenues first asking questions as you should and after a couple minutes he said snapped at me and said - 'you're thinking too much about this, it's just a bug.' then changed the question to 'you're seeing an increase in friend requests in India but a decrease in the US what's the problem?' So then I was working through my thought process asking questions. I wanted to understand how friend requests fed into a larger objective - increase engagement, increase user base, increase ad spending, so I can understand the direction we're going. He seemed annoyed that I asked that question he took me down this path that didn't make sense at all. In the end he wanted me to say that we should focus on continuing to increase friend requests in India because there's a higher addressable market but that didn't actually answer the prompt. When I pointed that out and said that was why I wanted to understand the objective, he realized his mistake laughed and said 'oh ok so I guess you can think long term'. ???? What? When I spoke with the recruiter afterwards she said he passed on me because of 'quantitative analysis' which was the only note he gave her and didn't even make sense. HM if you're going to present a case study, please be prepared. The whole thing was incredibly unprofessional and completely turned me off to interviewing at indeed for any other position.
