H and I talked more about this interview today and decided that the place wasn't in the greatest area, and that I should cancel the interview & look elsewhere.
I was on the fence about this until I called this morning to cancel.
The dude I was interviewing with answered the phone, and when I told him I was cancelling, he let out a deep sigh and said, "Let me guess. You've got another job?"
When I told him no, he said, "What the hell?" and hung up on me.
I'm thinking if he was that unprofessional on the phone, he probably wouldn't be much better on the job. I consider it a dodged bullet.
