Fascinating.
So, I'm confused. Did you pass on the job or not?
I passed on the job per the advice of the woman who had the job before me. Best lunch money I spent that summer. There are usually reasons for job openings. If the departing employee is still there, I've always favored taking them to lunch if it appears the job will be offered to me. It pays off with the knowledge of what the work environment is really like.
