Anecdotally, a former CEO of a company I worked at was a former McKinsey employee. Out of all of the "talk is cheap" CEOs I've encountered, he was the cheapest and would spare no opportunity to tout how he used to be at McKinsey, as though it was some badge of honor. Unsurprisingly, I consider him one of the least competent bosses I've ever worked for.
