The questions were challenging. I survived to the second round, which I think I did pretty well on. I did not get the offer, mainly because of the first interview, I think. I cannot tell exactly what questions they asked, but I would only say "Cracking the Coding Interview" is a book you have to digest. I found almost the same questions in it.

I cannot tell exactly what questions they asked, but I would only say cracking the coding interview is a book you have to digest. I found almost the same questions on it. Not exactly the same ones, but the key idea was the same. I regret not going through it before the interview. The interviewers were really nice though; it was fun talking to them.
