I have taken multiple of these take home assignments. One from Microsoft as well. What was a 2 day affair turned out to be a week long affair. I was asked to implement one of the iOS outlook features which involved multiple nesting of scrollviews in gridviews and what not. Took me 4 days and when I submitted the repo, the response I got was 'sorry this doesn't cut it and we can't proceed'. I mean, can't the reviewers at least provide some comment in the repo ? OTOH, I took a Facebook remote test that was timed (I think 30 mins) and the reviewer exactly told me why I didn't clear the test within 24 hours of submission. I don't necessarily agree with everything Facebook does but I really appreciate this level of response. So, I'll happily do a whiteboard test no matter how unrealistic it is.
