Algorithms challenge? Yes. As long the interviewer is ok with explanations as I don't bother retaining syntax most of the time, if it's not the language I'm using for day to day work. I can come up with a solution in C or even Assembly, but only in rough terms.
I'm also ok with a take home challenge if the scope is small, the intent to hire me is clear, and it will take only a few hours to complete.
