Meta Developer interview questions

Recruiter was helpful and accommodative to timing requests. Gave good overall description and expectations about interview process. Interview questions were not that difficult as imagined; however they apparently look for people who can code the most efficient solution at first go; which sometimes a game of luck. Interviewer was smart and polite; asking "logical" questions rather than trying to show off or stump the candidate sort of questions.

I got a phone call from a recruiter one day after I applied online. She asked me general questions about my experience and expectations. Onsite interview happened about 10 days later. I only talked to one guy, he once again asked me about my experience, about what I like about FB. Then he asked me one coding questions: given is a binary tree, write a function that returns Lowest Common Ancestor of two given nodes. After I did that, there was some time when I was allowed to ask some qustions about the company/team/ etc. Next day I received an email saying they have no position for me.
