The first interview was at my university. It was your typical 45-minute, face-to-face whiteboard coding-style interview. During the first five minutes, my interviewer introduced himself and asked me questions about myself. Be prepared to talk about yourself and your resume.

The next 35 minutes were spent entirely on one question. After arriving at a naive solution, I fine-tuned and optimized my code. The last 5 minutes were reserved for any questions I had.

I passed the first interview and went on to the second interview. They flew me down to HQ. This interview went horribly. The question was more difficult than the first interview, and my interviewer's accent made him difficult to understand. After the interview, I toured Facebook's campus and had lunch, etc.

First interview question: Dutch flag problem.

Given three color objects arranged randomly in an array, arrange them such that each object is together and their collective color groups are in the correct order.
