I only had a phone interview, but the woman conducting it was almost 20 minutes late and didn't even apologize for being late. They either had someone else already lined up for the role or she clearly didn't want to talk to me because she was giving one word answers and not telling me anything about the role. For a big corporation, I was in shock at how she treated me. Told me she'd get back to me the following week (which I knew she wouldn't) and I never heard from them again.
