"no correlation"? Nonsense. If you can't program a computer, I'll find that out. And if you can't program a computer, you wouldn't be able to do the job.

The point of my coding interview isn't to give a positive result if the candidate can program a computer. It's a test that's looking for non-programmers.

There might be "false positives", but if I avoid well-known memorizable questions, there won't be "false negatives".
