Reminds me of a previous job interview for an IT support role - back in the days of PCs being beige boxes. Took place in the staff canteen "because the meeting room was being decorated". Interview was in the middle of the day, so lots of staff going in and out eating their lunch.
One of the questions was "PC does not power up, no beeps etc., what's the first thing you would check?" I said power supply, try a known good unit. Interviewer told me I was wrong. I pointed out that he'd asked me what I would do, and I'd answered in that way - while he might try something else, *I* would do this. He still insisted I was wrong, voices were raised and he said it would be a RAM issue (with no BIOS beeps?!) - funnily enough, I didn't get the job...
