After leaving Intel a few years ago, my experience was that the grass is NOT greener somewhere else, it's just a different shade of green.
The first post-Intel company I worked for had NO leadership whatsoever. People did what they wanted when they wanted, the place was a chaotic mess. There was a mass exodus prior to my arrival, and I was part of another mass exodus when I left a year later which included all the people that hired me! The next company I went to work for was slightly better but mostly the same thing. Covid might have something to do with all that.
Finding the next "thing" can be challenging, and when you do, once you've established yourself and have tenure and seniority, good pay and benefits, it can be difficult to leave. In my day we called it the "Golden Handcuffs."
I saw the writing on the wall during my time at Intel and the only reason I check in on this site is to see if things have gotten better or worse in case I might want to return someday. Clearly it's gotten worse, much worse.
