Well, it's been a while since I touched this theme. 6 years ago, I launched a job board trying to fight ageism in tech (https://news.ycombinator.com/item?id=20252097)
It did super well in terms of upvotes and comments but not $ speaking (made $0)
This seems to be a current problem but what's the solution?
I have no problem interacting with younger ICs and even embrace my Dad-ness and Dad humor. I like mentoring and growing others, and I think it’s important to advocate for less experienced to get the lionsshare of the glory and attention.
For hiring, I just am not open about my age and mostly interact with people virtually. I don’t have my early irrelevant jobs and don’t show my graduation dates. So I haven’t seen it as a problem.
