I got 2 interviews one was on campus .After my first round almost after 2 weeks they invited me to their office at Andover for final interview. It was very smooth.

I had just one 30-minute interview in person. The interviewer (who became my boss) was very kind, and asked about my experience in CS classes as well as projects. He asked me a few technical questions as well -- no writing code, though. Just some knowledge questions that a decent CS student should be able to answer.
