Meta Software Developer interview questions

Was contacted by a recruiter. Set up a phone interview; had weird telephone problems, couldn't understand my interviewer very well. Did some general algorithm questions in Python that were well-suited to a phone interview, but wasn't pleased with my performance overall. Recruiter contacted me back to do a second phone screen - said there "wasn't enough of a signal" the first time. Apparently this is not common. Second phone screen had problems with the collaborative edit software we used for coding - I had to stop, copy, and repaste my code several times for some reason. Again, the questions were well-suited to the format of the interview. Thought I did better but no better than an average performance, probably. No offer, the whole process took about a month (but I intentionally delayed the phone screen for personal reasons).

I got the interview by referral from a teacher who was in contact with the recruiter. The teacher gave my contact to the recruiter and a few days later I received an email to schedule the first skype interview. The question I mention was from this interview. I succeeded and got another skype interview, in which I failed. Pretty straightforward process, though.
