The interview process was pretty smooth but kind of long.

It started with a quick phone interview, followed by an invitation to an onsite interview.

The phone interview was quite easy. I am not a CS major, and the interviewer was aware of this, asking questions tailored to my background.

I had less luck at the onsite. The interviewers seemed to be expecting a solution I hadn't encountered before. However, it wasn't their fault; the question was still relatively easy with good interview preparation and should be very doable with a solid CS background.

I completed two rounds at the onsite and was subsequently sent home, which meant I did not receive an offer as I had expected.

Still, it's a well-run and not too difficult process.

Prove that sqrt(2) is irrational (was only asked this because I was a math major).
