He was down-leveled to a first level manager at the company you are at? He accepted this? Why? Do you think he / the new company chose wisely? What ended up happening?
He was a great manager, he’s since moved up the ranks but he’s still at the same big tech co. So from both the company’s and his perspective, I suppose everyone’s happy.
> It might be nicer to go work for startups, acquire experience there as you build everything from scratch across the whole stack, then get hired at a high responsibility position
You mostly don’t get hired into high responsibility positions at big tech from startups, unless you’re acquired by them directly.
There are some notable exceptions obviously, but those generally require you to be some sort of leading domain expert.
