The interview process starts with a phone screen. During this phase, you are asked a simple programming question and must answer it on a shared document.

If you pass the phone screen, you are invited on-site for a panel of interviews with five or six different people. These interviews typically cover either high-level design questions or more technical algorithm questions.

I was invited back for a second day of interviews because the company felt they didn't get a good enough sense of my technical skills the first time.

I was asked about my experience with MongoDB and to compare and contrast the tradeoffs of non-relational databases and SQL databases.
