You wouldn't be asked to "fizzbuzz". You would be asked to write an extremely trivial program, which would take you about 3 minutes.

Also, if you have guaranteed years of experience, fizzbuzz isn't for you. However, a suprisingly large number of applicants who can write an impressive looking CV can't write it.

I've also "heard" that the ratio of people who fail at fizzbuzz is truly disturbing even if they have impressive CV's.

It makes me wonder, though. Has anyone ever just admitted they failed at fizzbuzz here on HN?

I can imagine someone bombing it if they're nervous or if they forgot the modulo operator in their language of choice and got lost doing it an "ugly" error-prone way because they were too embarrassed to change tack once started.

If someone reasonably competent were to spend years working with some limited api's, on a codebase that has hundreds of man-years on it, could they fail at fizzbuzz when asked out of the blue? I think so.

I've wondered before how many of the "OMG tons of candidates can't fizzbuzz" anecdotes come down to messing up syntax or forgetting the name of something in the language they're using and mixing in something from another language, or making a plausible but incorrect guess. I could definitely see doing those things in an interview, and I've usually been considered the "smart one" or one to come to with weird/low-level/architecty problems where I've worked. Hell I know for a fact I once used the wrong friggin' method invocation syntax in an interview. That stuff barely has any place in my long-term memory, I mostly rely on context to get it right when doing real work.

I can also see a lot of folks forgetting about the modulus operation and doing something uglier and smug interviewers deciding that means they're a fraud and/or an idiot. I've only used it a handful of times in real code, in... oh man, over 15 years. If it hadn't been (for some reason) among the first things I picked up when first learning to write code it might not be as relatively-well stuck in my head as it is.

It depends—when I was at one of the really visible companies, it wouldn’t have surprised me if as much as a third of the people I screened had lied on their resume. I’d ask folks to write functions to count the number of times the letter ‘a’ appears in a string, stuff like that. Did not need to compile or run.

I had a person break down and confess, and we spent the rest of the interview talking about how their codecademy lessons were going.

That turned out surprisingly wholesome.

I really don't think it is very many. There are clear patterns of failure for fizzbuzz - the biggest is the "copy-paste programmer" who sees a blank canvass and just has no idea where to start. Then you have your people who can write conditionals but can't reason about them - they will very often end up with a solution that compiles, but always prints the number no matter what, or never prints FizzBuzz, or some other obvious error that should be apparent on a quick review of ones code. Most of these people also take 10-15 minutes to write it out, where competent programmers consistently bang it out in five minutes or less. (And yeah, some of them probably know it by heart by now. Oh well.)

Screening someone who just absolutely can't program at all is, IMHO, by far the worst part of technical interviewing.

There was another HN thread recently where posters were ardently justifying lying on their resumes.
