Applied for the position through my school's career services website, and got called for an interview about a week later. First interview was very casual with someone who was in the same position I was interviewing for. Exactly 2 weeks later I got an email for a second on-site interview that would last about 2 hours. Had 3 different interviews, each focused on something different: 1st focused on team work and experience, 2nd on personality and fit at Facebook, and 3rd with the same interviewer from the initial round about the specifics of the position. The recruiter was very friendly and gave me a tour of the office, and sat down to chat with me at the end. I got a call the very next day saying that they wanted to move forward and check my references, and I really appreciated the promptness. Early the next week I got a call saying my references were good, they were getting my offer package ready and would be in touch by the end of the week. In the mean time wanted me to talk on the phone with the person who would be my direct manager. He repeated a lot of the questions from the on-site interview, so it was simple. Didn't hear from them at the end of the week, and after freaking out all weekend finally called on Monday and found out I didn't get the job. Turns out they wanted someone with more experience, which even the recruiter admitted should have been made clear from the very beginning and was sorry for leading me on. She was very gracious with feedback about the interviews and told me to keep in touch. Even though I was caught completely off guard when I didn't receive an offer, it was a good experience overall and I will apply again one day.
