Funny you mention that. Looking back, there's at least one company that I should've left on day 1. The flags now look bright red. But my thinking back then was that I'm probably wrong with my understanding of the situation - maybe this, maybe that. There's an emotional undertaking when you leave your old role and show up at a new place and there's bound to be some struggle.

That place was a disaster. I mean the half-the-team-ends-up-leaving kinda disaster.

Figuring out when "it's you and not me" takes a lot of introspection and that's usually accompanied by a lot of self doubt. You can't really tell except long after the fact.
