The first round is a phone screen. It's reasonably chill: write clean code and communicate well. They don't compile or run your code; they simply tell you if something is wrong, so you need to debug by inspection. Otherwise, it's a really fun interview.

The final round consists of three interviews, similar to the phone screen but a little harder. It's the same deal: communicate well, write clean code, debug by inspection, etc.

After the first two rounds, they will tell you if you are progressing to the third round.

They asked me not to disclose.
