It was really weird, but a higher up in the company interviewed me and right from the get go was rude. I know that sometimes some people use that as a tactic to scare interviewees but it was unpleasant.
Also this person sat through the whole 20 min interview and secretly vaped. Which was an odd choice. I get maybe he didn't get a break through the day and vaping isn't the same as smoking. But I wonder as an interviewee I would be accorded that some consideration if I had chosen to vape through the interview. Needless to say, left a bad taste in my mouth (pun intended)
