I realized recently that I keep a mental list of good teams to refer people to, but that information is not commonly known! It can often be very hard to tell if a team will be supportive, have work life balance, be full of good people, etc. And if you've had bad experiences at several companies, it can be easy to think all teams are that bad. Not true!
A few disclaimers: Keep in mind that this recommendation does not represent the companies as a whole (unless the companies themselves are very tiny). But in a large company, there are often pockets of good people. I also haven't met everyone on all of these teams. It's more a judgement that I make speaking with some people on the team or people I know who've worked on the team-- seeing how happy they are and seeing what they say about it. I feel I'm a pretty good judge of character and work environment. Keep in mind that not everyone is hiring (but some are!). Lastly, this is mostly from my network, which comes from me living on the West Coast of the US most of my life with a stint in Denmark. Just a few companies!
