Somebody here commented long ago about Bill Gate's style of management which reminds me of this piece. If you presented something to BG he would start asking questions and get deeper and deeper. He was merciless. It seemed that he was just making sure that you knew what you were doing. So your really had to be prepared. Someone as knowledgeable and smart as BG was able to keep the Bull shitters out of the development org.

I think what I am remembering is this story from Joel Spolsky. Good read. https://www.joelonsoftware.com/2006/06/16/my-first-billg-rev...
