I was given a take home problem under the guise that they did not do live whiteboard coding interviews. I did the problem, and it was impressive enough to get me on the phone. I was impressive enough to get from the phone to an on-site.
What do you think happened at the on-site? Yup, standard whiteboard coding interviews. Nervousness and pressure means I didn't have a very good showing, although I did solve the problems.
Was told that very day that I wasn't going to be a good fit. Any feedback from the interview where we finally did talk about my solution to the take home problem would not have been taken into consideration as I was told it wasn't a fit right after that interview and nothing was said between the two people.
I really do think that the only thing they found out about me was that I can not do those sorts of problems while nervous and under pressure. What they didn't find out was anything about my actual abilities.
