I've heard of plenty of companies publishing gender and ethnicity breakdowns of employees. I've never heard of anyone doing that for age of employees sadly.
You just have to look at one of those "company pictures," taken at offsites, or whatever.
Lots of smiling young faces. Maybe one or two gray heads, and you often find out they are Principals, in one way or another.
One of the dirty little secrets of tech ageism, is the ones doing it, are often older folks, themselves. IBM has been caught doing it, and the impetus came from their (quite gray) C-Suite.
That could be accounted for by the older folks not being able to attend the meetups as easily, due to family obligations and whatnot.
Especially people in their late 30s to 40s with kids who haven't left yet. I suppose there's really no too old to have kids who are not yet independent, given that a non-negligible percentage of millenials and zoomers will still be living with parents and whatnot
What do you mean? Are you young and they were interested? Or a senior level developer who was older and they were interested?
