Developer: Is the job for someone who spends their days doing timed code quizzes?

If it is then it is acceptable. If it isn't then it seems asinine.

For me myself, if I had a literal clock there ticking down then it will take me twice as long and I'll do a much worse job. There's a lot of people who cannot program under high stress situations like that (and a job interview is naturally quite stressful already). So expect to dismiss a lot of otherwise great candidates.

Maybe the interview process should be based around the job you're employing them for rather than for trivial games that only test someone's abilities at completing those exact type of task. Crazy I know, but maybe just maybe it makes sense.
