Reviewed resume & asked a few questions about my background. Was able to speak to their product that was to be sold, however the interviewer manager abruptly stopped the interview & walked out, leaving me with the HR rep in shock. His reason: I was wasting his time since I didn't have direct diabetes experience even though I could answer all of his scientific questions. I have a science & healthcare background. Very inappropriate behaviour. Interviewers should realize that as much as they are interviewing, prospective employees are also interviewing them. Not a manager to work for in this case.
