Interview
I talked to a recruiter at a career fair and they got back to me asking to interview about a week later. About 3 days later I had two 45 minute interviews on campus over two days. The entire process was smooth, with the HR people being quick to respond to emails and set up interview times.

Question 1
They asked a long question about string manipulation, requiring most of the interview time.
