This is probably my worst interview experience. There was a bunch of inexperienced and incapable interviewers who can't explain the question they posed or answer any follow-up questions, and who don't understand or explain the sample output they provide. The recruiter is completely unprofessional as well, and she won't show up for the scheduled prep call or respond to any emails. Don't bother wasting time here, even if it were to test your skill. It is just a complete waste of time.
