Essentially I was asked to "speak out code" specifically it was a very odd problem involving a binary search with a weird twist. A binary search isn't a difficult problem, the weirdism they added made it hard. Long story short, I got a correct answer, but the recruiter not understanding english very well did not think I did. (I later confirmed with many senior engineers who said yes I had a correct solution) I don't know what possessed them to have a tech interview without a google doc, or simply email. Speaking out code is as stupid as writing out code in college exams on paper.
