College recruiting. I flew out for on-campus interviews and had four on-site interviews. I was contacted one day afterward with the results. The interviewers were all very friendly and shared why they chose Microsoft over startups, etc., and why the position was exciting. This definitely changed my impression of Microsoft as a great place to work and persuaded me to join the team over a startup offer, even for the SDET position.

Nothing too difficult. I wanted to know how to track duplicate words in a book.
