The interview is very technical. Studying the CLR algorithms book in advance is the best route to take before submitting your resume.

There is typically a screening interview by HR to find out if the candidate is a good fit attitude-wise, followed by a code test, and then potentially two days of in-person interviews.

HR may send a candidate home early if the interviewers do not think the candidate is a good fit for the position.

I don't recall a specific question. Even if I did, I don't necessarily believe posting it online is a positive step for the candidates or the company. As I mentioned, studying the CLR book is the best route to success.
