Applied via LinkedIn and was contacted promptly by a recruiter to set up a phone interview. The phone interview went well; she was very cordial, said I answered the technical questions well and set up an onsite interview for next week. The format of the onsite interview was to have each candidate pair off with an engineer in a separate room and then rotate every 30 mins so that each candidate is interviewed by each engineer. I signed a paper stating that I cannot disclose the technical questions. However, I'll say that my second coding question, given by my second interviewer, was difficult. The guy had 1 and only 1 answer he was looking for. He told me my solution was "completely wrong" (which it wasn't ....) and didn't explain why. That was after he had sat there, watched me explain my procedure and asked relevant questions that I cleared up for him. I was baffled and shaken up. After he left, the recruiter lady came in the room and asked me how I thought I did. Why she asked this, I have no idea, but she went on to tell me that I wasn't doing so well and the interview was going to be cut off early. It had been 1 hr so far and the interview was supposed to go 4 hrs. So I took the walk of shame through the Groupon office area to the exit. She had to make things more awkward by following me into the elevator because she needed to go to the first floor. I tried to crack some lame joke to lighten the mood. Then I walked to the nearest mini mart and bought a 24-oz Milwaukee's Best Ice to drink out of a paper bag while I waited 5 hours for the next train back home.
