The interview process consisted of three rounds.

First, a behavioral screen with the recruiter.

Second, a technical phone screen.

Third, an on-site interview. One of my on-site interviewers was the CTO, which was a cool experience. The questions were on the easier side compared to those at companies like Google and Facebook.

Here's where it gets strange:

I asked some of my interviewers a standard question about work-life balance. After my last interview, the recruiter confronted me directly about those questions. This indicates two things:

• They documented the questions I asked my interviewers.
• They consider questions about work-life balance a red flag.

In my opinion, that's a red flag about Mongo. I ended up accepting an offer from a larger company with a better salary and work-life balance.
