I worked in engineering at Google from 2007-2015. I conducted … I can’t remember, definitely more than 100, maybe something like 200 in-person onsite technical interviews. (In addition to loads of phone screens, but I couldn’t see those people.)
Not a single person wore a suit.
If anyone had, I would have been very surprised and I would have immediately started wondering what other memos that candidate had not received.
… by a sniper?
