MongoDB interview questions

A recruiter reached out to me and we had a short phone call to talk about my interests and experience, the position, and my potential fit. The recruiter gave me a lot of information about the teams and intern program, but she sounded really unenthusiastic and tired, like she was just going through the motions. Next was a 45-minute technical phone screen. This interviewer was also very cold and unfriendly. I was asked conceptual data structures, OS, and database questions. Then I was given 3 light coding problems. The interviewer was completely silent after asking a question, even when it was clear I was struggling or confused. He sounded bored like he wanted the interview to be over. He didn't comment on the solutions or answers I provided after I did them either, so I had no indication of how I was doing. The days of the one-way interview are over, it's as much an interview of the company as it is of the candidate! The experience left a bad taste in my mouth of the type of people who work at MongoDB and I won't be applying again.

Friend referred me to a university recruiter, who called me for a brief 30 minute chat. Then I had a 45 minute technical interview, which led to the recruiter calling me back and scheduling a 3 hour Skype call with three different engineers. This was instead of the onsite interview, which I've heard is the same experience. Everyone was very polite and great to talk to.
