I applied at a job fair, then had an on-campus interview the next day. After a few days, I heard back, inviting me to fly in to their main office for an on-site interview. The experience was very fun. We were given free meals and shown around the offices, which was also very enjoyable. The intent was obviously to impress us with the company's work atmosphere and amenities, and they succeeded. We had technical interviews as well as some other activities, and were given more freebies.

I was asked two questions. One I take to be a pretty famous interview question, and one that I have not since heard of. The interviewers were very nice and gave good hints to help me along, but the questions were very difficult.
