The ability to troubleshoot is an extremely valuable skill, and almost no one evaluates that in a technical interview.
Like, if you have a technical career, when was the last time you designed, made, or programmed something that worked perfectly the first time? Probably never, am I right? Most of your time is probably spent trying to figure out why the fuck some thing doesn't work correctly, right?
Design your interviews around that, not coding on a fucking whiteboard.
