First year software engineer with no friends

So I landed my first job as a software engineer, in a software i didn’t study. The company is great, people are too, I even have 3 days of remote work each week, good pay and 20% pto. On the job it self I don’t really have any complaints (even if it’s a lot of work, it’s well defined), I was expecting something more boring, but my team is very collaborative and friendly (we do have a hard time describing stuff to our product engineers since our stack is not mainstream and a bit hard to understand).<br><br>So, everything is great on the work side.<br><br>But I’m feeling a bit down since I had not an ounce of contact with my coworkers outside of work (texting, phone calls, lunch, etc). I honestly don’t even know what they like or what they do after work. I tried to make them drink a beer after work, but they didn’t. I asked if they wanted to grab lunch, they said yes, but it never materialized. I have lots of acquaintances, but everyone is super busy at work and after, and I even had 2 birth announcements from coworkers I’ve never met.<br><br>Outside of work I don’t really have friends. I was busy studying, and I never had time to build a life out of work. I’m not even sure how to build a life outside of work.<br><br>So, what do I do to reach my coworkers? How do I even make friends outside of work? <br><br>How do you make friends? <br><br>How do you keep in touch with coworkers outside of work? <br><br>Any tips would be appreciated, I’m getting really anxious about this.<br><br>Tl;dr; I have no friends, need help making them.
