Discussion on question by Neil Meyer: Can I avoid informal personal interactions at companies that offer free lunch?

"Years of preparation to get to the point where you can do Web development" seems like a red flag and misunderstanding how software development actually gets done. Once your career progresses beyond the entry-level stage, you will probably be spending less than 50% of your time actually "writing code," and maybe as little as 20%. The rest of your working time will be interacting with other people.

"Should I just get over it" - definitely. Nobody is going to make you eat a free lunch. Nobody is going to force you to talk about personal issues with colleagues. Nobody is going to force you to build a personal relationship with anybody. You appear to be completely new to a professional workplace, since your views seem rather unusual. My advice is to give a normal working environment a chance, or instead choose a company that lets you work from home by yourself.
