The recruiter mailed me and wanted to know my interest in FB. He possibly found my email ID from a Programming Contest Site. It was a surprise mail because the same recruiter wanted to speak to me a year back, but never called despite scheduling times on three occasions. But this time he did call and set me up for a Phone Interview. I got passed two Phone interviews, as I was scheduled for a third one. Few days after the third, I get a thank you mail from them saying I don't have the right skill for the positions that's open now. Since I got the bad news after the third interview, I would mention that one in a bit more detail. He called on time. He knew that I got passed two rounds and then for quite some time we discussed about the kind of things done in FB. He reminded me that he is in a very responsible position and is the right man to ask for in depth question about FB. His overall attitude was friendly. After the talking, he asked me two coding question and I had to code on Collabedit. The problem difficulties were easy, but after coding he asked me to improve on certain section of the code. There was also a requirement that the code must compile. Now, I was typing on an Web Based editor without any compile option and I am not sure if its considered a big skill to have the code compile on first type. From my part, I would say I did well if not excellent. They mentioned they would consider me when posts open up. Not sure if this is how they mail out Reject mails, or they are considering my positive aspects of passing two phone rounds.
