> You are a senior software development lead at an A-list firm. I ask you to solve a fairly basic coding problem which takes a college grad 15 minutes, but you get stuck on it for an hour. You stumble your way through various possibilities, write atrocious code and then mumble an apology about how you “don’t have the opportunity to write code these days”. You would have been red-flagged in a real interview in the first 5 minutes. In my experience doing 50+ real interviews, even good programmers can fail a white board coding question. Experienced candidates tend to fail it harder, since they tend to be more rusty at interviewing than new grads. It's a different experience to real-world programming. A good analogy is a micro-benchmark. What are you trying to measure here? It's quite possible you end up measuring how a candidate does under pressure rather than actual programming skill.
