The way it was put to me is the modern tech interview is to the job as the SAT is to college. They don’t require the same skills, and performance in one isn’t terribly predictive of success in the other.

Do not doubt yourself based on your interview performance. If it’s something you care about and you have the time, do your test prep properly: big O, tree traversals, etc. etc. etc.

I’ll add that as a primarily functional programmer who’s applied for multi-paradigm jobs, I’d say a lot of the answers I’ve been expected to give were quite absurd.
