Once in an interview a senior designer walked in on my interview. They were introduced. Hung out for a minute. Wrote something on the whiteboard, then left. My interview ended, I was left in the room for a minute and I stared at that frackn whiteboard wondering what that was about. I didn't get the job, but I had to assume this was something that senior designer was into--something they cared about, something they used, a skill they wanted to manage, a subject they wanted to discuss. User ItsMe000001 says he was asked about a 'right join', choked during the interview, was still hired, and later became the go to guy for writing queries. If a question is in the interview, it's relevant to someone in some way unless it's a psychological mind-frack test. So the question would be, Who was also hired, and later had their head flipped?
