I have never come across such a demotivated, tired, and negative interviewer in my lifetime. The interviewer didn't even ask/provide any intro; he jumped directly to problem-solving and was least interested in answering my questions at the end of the interview.

I usually judge a company by its employees, and having interacted with that interviewer for an hour, I secretly hoped that I wouldn't clear the interview. I was more than happy when I got to know later that I hadn't cleared the round.

One month later, I joined one of the US's top tech giants at a much higher salary than LinkedIn could have offered, plus all my interviewers looked alive, motivated, and connected. I am sure that I won't be bored to death (unlike the LinkedIn interviewer) while going to work each day.
