This interview could have been done by a robot. The interviewer used the STAR interview technique..you know the kind... "tell me about a time". The questions were random with little centralized focus. The overall impression was very cold. The interviewer had no personality, never laughed, never showed a human side, was very short and robotic.
My advice to Amerisource HR would be to remember that as a company you aren't just interviewing a candidate...the candidate is interviewing you, and well...you failed.
