My first interviewer was very cold. He seemed uninterested in the interview and didn't make an effort to make it conversational or engaging. He left me to have my lunch.

They had asked what kind of lunch I wanted ahead of time, and although there weren't many options, I figured I wouldn't be hungry anyway. I requested the vegetarian option, thinking I'd pick out the vegan elements. It had bacon in it, so I decided against eating it.

My next interviewers were also quite hostile.
