MongoDB Software Engineer interview questions

First round is a behavioral screen by the recruiter. Second round is a technical phone screen. Third round is on site. One of my on-site interviewers was the CTO, which was cool. The questions were on the easy side compared to Google, Facebook, etc. Here's where it gets weird: I asked some of my interviewers a standard question about work-life balance. After my last interview, the recruiter confronted me about those questions point blank. Which means that: a. They documented the questions I asked my interviewers. b. They consider questions about work-life balance a red flag. That's a red flag about Mongo, if you ask me. I ended up accepting an offer from a larger company with better salary and work-life balance.
