It was an on-campus interview. The company announced itself via email, allowing for an initial pool of resumes to be collected. From those, a number were chosen for an on-campus interview. I came in, and the interviewer was very cordial and easy to talk to. We spent a good bit of time just discussing various tech interests.

We immediately started with a coding problem, then moved on to a number of design questions and some questions about my background.

Fairly easy, I made it through to the second round, which is to be flown down to their Microsoft campus for an interview. They haven't called me back yet.

Reverse the words in a string.
