I'm sorry to hear about your experience. I've been on both sides of the hiring process. There definitely are some tactless, rude interviewers out there. I have tried to use my bad experiences being interviewed as a lesson in what not to do.

I remember once these two guys interviewed with were very accusatory. Everything was phrased as, "well, your resume says you know how to do this, but do you really know? It made me really uncomfortable. I didn't get a call back and I can't imagine wanting to work there if I did.
