Everyone thinks they are google, if you are like 90% of tech companies and have a crud app, maybe a couple mobile apps and a few backend systems and admin tools, a radical idea is to involve your engineers in the interview design process and tailor your interview to the actual job they will actually be doing. Front end engineer and your stack is react? Pair with them on fixing a UI bug, backend engineer in rails, pair with them on a adding a basic endpoint. You get the point. If an engineer pairs for 30 min with someone I can pretty much guarantee they will have a strong sense of how they work and whether they know their stuff. I really don’t know why we treat this like it is some impossible task to determine if someone can do the job, just try doing the fucking job.
