> When people talk about things you can't say in tech companies, being in a greek organization is one of them. I would never advertise the fact that I was in a fraternity for fear of how people would perceive me.
I was in a fraternity myself and I don't bring it up unless it's relevant because I'm an adult and nobody cares anymore.
People will only perceive you poorly if you bring it up when it's not relevant and that's because they'll, rightly or wrongly, think that you never grew up.
If anyone actually does care, it's probably a shitty company culture. Why would anyone care about your social activities at college post graduation and working at a real job?
There's good reason. Fraternities are the exact opposite of meritocracy. Their very reason for existence, in fact, is to subvert meritocracy through cronyism and nepotism for those who can afford it. Because of this, people engaged in strictly meritocratic work (science and engineering) find that whole world repulsive.
There may be some like that but there are plenty that are not. I don't remember anyone getting in my fraternity that way and we averaged over 100 members at a time.
Richard Feynman, John Bardeen, Linus Pauling, and Kary Mullis were all in frats. That's just from 5 minutes of googling famous American scientists I could think of, I'm sure there's more.
That said, I don't think we can judge people in the past using modern ethical values and it doesn't take away from his achievements.
I think part of the problem is what is meant by "fun" in the workplace. Fun at a workplace should mean something like you enjoy being there, are interested and challenged by your work, and have a cohesive team that works well together.
If you are struggling to have "fun" at work without creating the perception that it is like a fraternity, then I think you have likely missed the point entirely.
