Facebook came to my campus career fair where I turned in my resume. I had an onsite interview in New York which went well. It was completely a technical interview with only programming. I was asked 2 questions - the first was a simple reverse a signed integer, the second was a harder pattern matching problem that could be solved using a prefix tree. I was invited to a second on-site interview in Menlo Park. It was a long flight across the country and in hindsight totally not worth the time wasted - I skipped classes and turned in homework late as a result. The on-site was awful. My interviewer showed up late and then proceeded to ask me a very simple question about printing the paths to nodes in a binary tree. Coded it up with some minor corrections (since I was white boarding and you miss some stuff when you're face is glued to a wall). He then extended the question but cut me off because we ran out of time (this was completely his fault since he showed up a good 15 minutes late). They proceeded to give me a tour of the campus and talk with current engineers. It would have been fun if it hadn't been for the bad interview. Overall, I got the feeling that they're a large company and are definitely not as agile as they were a couple of years ago. Engineers were very complacent and talked more about their great perks than personal growth. In the end, I think I got caught in the interview anti-loop and had some poor luck. Promptly rejected. I really wish I hadn't wasted 48 hours flying for that sad excuse of an interview.
