I couldn't agree more with you. This seems like an old model of assuming that those under 30 can't work well with those over yet they are expected to enter a diverse workforce. I'm 37 and in my 4th month at a school similar to 42 in SF. I'm glad that Holberton School didn't have that age restriction or I'd still be looking for another option.
Yea, with you on that. 32 and back in school. There are a few folks that are late 30s, early 40s. Sure majority are early to mid twenties, but that hasn't stopped anyone from working together.
