Ask HN: Do you expect interviewees to “ace” whiteboard coding exercises?

I know that whiteboard coding exercises are in low regard these days, but as someone who's currently looking for a job, I can say they're still widely used. I personally never had a problem with being asked to write code on a whiteboard as part of an interview. Partly because it used to be understood that the point of the exercise was not to write runnable and correct code, rather it was simply to convince the interviewer that under ordinary circumstances (access to an actual computer, sufficient time) that you could produce code that was both runnable and correct.

However, the last three whiteboard coding exercises I've done (two at Facebook and one at a small startup) seemed to be judged much more harshly than what I'm used too. I don't think I "aced" any of them, but had I been interviewing somebody that performed at the same level, I would have said "good enough" and passed the person along for further consideration.

Now some extra information: All three interviews were in Seattle, two of the interviewers for sure were ex-Amazon people (which I mention because I think it might be relevant), and I managed to get hired at Microsoft back in the 90s and at Google in the mid-2000s. I was not hired at Amazon back in 2002-ish, however.

So anyway, I'm wondering: Have I just not been doing as well as these interviews as I think, or has the industry moved the goal posts on me?
