That’s pretty much how I remember the place. Sometimes I wonder why I left, and a second later I remember all the reasons it was a good decision for me.
As for why people don’t leave - it’s not that easy! Even if you’ve avoided the golden handcuffs it’s extremely difficult to get the time off to interview anywhere! Between the crazy schedules, impossible swap system and the need to get to a multiple day interview elsewhere, you need to be incredibly lucky to have the stars align!
