I was reluctant to give a negative experience here, because the recruiter and scheduler were very timely and helpful throughout the process. However, being thrown what I now know to be a very challenging coding right off the bat leaves a bit of a bad taste in my mouth. Unlike the plethora of videos that exist about the interview being a collaborative process, where one talks out loud to show your thought process, I was given, "Here's the problem. Do you understand it? Ok, I'll sit on this call while you solve it." You might as well have given me a Hackerrank and be done with it.
