I tend to do much of the phone/person screening at our shop. I'm surprised how many folks try to bluff their way in. You ask a big-O on maps, lists, and the different implementations they will rattle off the (correct) stackoverflow response immediately. Hit them with basic questions, like handling an exception or closing a resource/JDBC connection... and can just get blank stares. Codility and Leetcode... screen that folks can code, but the folks who tend to be good at a quick grind don't always produce good code. Not a huge fan of it. I don't even look at the report anymore.
