Religious groups, volunteer organizations, charities, clubs in college, extracurriculars in high school, the military, van life, swingers clubs, outdoorsmanship clubs, working at renaissance festivals, clubs for specific sports like skydiving or fishing (not gyms, gyms are for working out with people you already know well), private events in intimate settings where you are introduced to an existing friend's other friend group, and your extended family are all places you can find people to have these kinds of social relationships with. People tend to cluster around activities they enjoy where they can interact with other people who at least have enough in common with them to enjoy the same activities. They are more open here than anywhere else in the modern world to forming new social bonds.

Better places would be if you were raised in an insular high-trust community or if you were trapped in a traumatic environment with them such as a siege from which you ultimately collectively escape by working together. These are not reproducible.

You might need to work on becoming more sociable if these sorts of places aren't working out for you.

That sucks that the people you work with only care about your credentials, though.

I'm an old man, unfamiliar with modern culture, but back in the day we used to go to bars or taverns for this kind of socializing. Maybe it's coffeehouses now?
