A Facebook recruiter contacted me about a year and a half ago, and when I was ready, I told them to proceed. A telephone interview was then arranged.

I wish the interviewer had been more courteous and had corrected me earlier when I was explaining some test cases after seeing the question. This would have given me a better chance in the interview.

Interviewers should consider that the problem they are asking is best known to them, so it may not be very clear to the interviewee on the first try, especially over the phone.

Some confusing questions cannot be disclosed.
