OpenTable Software Engineer Internship interview questions

I applied at my school's career fair, then a month later, I got an interview request for a 60 minute interview on my college campus. Then two weeks later I was invited for a 3-hour onsite in San Francisco, where I interviewed with 3 engineers for an hour each.

Spoke to recruiter at college career fair and was invited to on-campus interview shortly afterward. The interview was about 45 minutes and pretty casual, I got an easy technical question so moved onto the on-site interview. The on-site was basically a whole day: coding challenge in the morning, and three interviews in the afternoon - two technical, one behavioral/culture fit. After about a month, they got back to me with an offer.
