non-regretted departure?
Is that something like "Quit my job at Google, middle fingers in the air," or what?
Disagreed (reasonably politely but persistently with lots of data) with upper management about what became a key technology to Google a year after I left. Got told to shut up about that technology or leave. Chose the latter and made a successful career out of being an expert in that technology. Found out later through my contacts that HR slammed the door behind me.
Jobs aren't scarce, but talent is. I've never gone for want of employment and Google blind-allocated me into a boring gig I hated. And yes, I'm very anti-social when I'm coding. I wouldn't want to work for a company that considered that a negative trait.
