Thus Google is/was the #1 destination for ex-McKinsey folks. Generally speaking, mgmt consulting attracts more risk averse people than otherwise, so this is somewhat natural (in fact, my risk-seeking friend who joined the firm was surprised that so many people were risk averse).

But there are plenty of people who leave the firm to go to mid sizes places or places with less cache, but at a relatively high position in the corporate chain.

They also leave to join growth phase startups as well.
