I understand what you are saying. I can see using a coding test as a signal but it would probably be foolish to use it as a filter.

There are lots of critical skills and qualities for which there are no simple tests. For example, an excellent mentor could level up all those around them and provide far more value than a great programmer with weak interpersonal skills. In the end, it's a gamble.

It is so pleasant and so rare to agree with people these days. I agree with you.

It is signal for me. My interview consists of many areas beyond coding. But coding is one I explore too. (like write a methods with two sequential loops and single if in your favorite language.) You would not believe, some 30% people fail.

Mentor or programmer -- we need both qualities in the end. both extremes are harmful. To be a good mentor, one need to have respect of colleagues -- and it comes from contribution too.

gamble -- agree again.
