I was in tech for 35+ years - yes, I'm old. I'm out now not because I don't like the work, I really do and I'd prefer to be doing interesting work. I'm out because I'm tired of the interview games that are played now - that and I've pretty much got my retirement nestegg saved up.
Tech has definitely changed. Having to go through 8 or 9 rounds of interviews for one position only to find out you weren't selected at the end (that is if they don't just ghost you) wasn't a thing when I got into this line of work. In fact most of my early jobs I got after only 1 or 2 interviews for maybe a total of 90 minutes.
Part of it is that companies are just so damn afraid to hire the "wrong" person that they just can't make a decision. Part of it is because there are so many people looking for tech jobs right now that companies feel like they can play these silly games. More people need to refuse to play.
