Agreed, i spend a couple minutes verifying their resume through fizz buzz type questions. Then figure out how they react when they don’t know something. Make sure they can collaborate. At this point you get a decent idea of how that person fits, or doesn’t. It really only takes 20 minutes of tech questions and 10 of shooting the shit. Pro-tip for getting hired with most interviewers is to get them to do most of the talking and parrot back what they say they want.
