I was contacted for an interview on my university's campus. We discussed my research and interests, and I received a follow-up interview at Microsoft's campus in Washington.

I was flown to Seattle with a group of other interviewees. The following day, we were all driven to the campus and taken to a conference room. We would be stationed there throughout the day while being called out for four separate interviews.

The interviews themselves were not difficult, but only after the first two were any of us even told what department we were interviewing for: Microsoft Office. Since this had nothing to do with my interests or research, I was very confused. When questioned, the interview organizer just apologized.

Interesting question regarding tries and spell-checking.
