I avoid doing interviews, but I've suggested fizz buzz a few times to people I've worked with because it's so simple but once outside the environment of your usual IDE seems surprisingly simple to screw up.
Whenever I've suggested it a usually more junior guy has scoffed at how trivial it is... I'm yet to then have one supply a complete and flawless solution. These are from people I work with, respect and happily rely on to be able to code. Their recognition that the problem isn't so trivial for themselves is the only thing I've got out of it - I'm no closer to understanding if it's just a poor test or not.
There first time I came across the problem was as a candidate and I screwed up the upper bound of my for loop just because I was slightly thrown by starting from 1 instead of the almost obligatory zero. Naming things, caches and off by one errors.
My worst candidate experience was only a couple of years ago when they wanted me to reason about booking cinema tickets over the phone (like it's the 90s?!) I've never booked cinema tickets and I think they thought I was joking, but they went at me for at least half an hour on what users would need to supply other than location, film title, date and maybe time, to begin the process of booking tickets. Why they didn't just tell me what attribute they were after I'll never know - eventually they just wrapped it up.
