I've worked as a developer where we weren't expected to talk to each other for non work related stuff. To the point where it would be brought up by managers, or even an employee pulled and told they were talking too much.

You are expected to go in, head down, do your 8 hours work, go home. Non work stuff was expected to be kept to non work hours.

I've also worked at highly social workplaces, drinking on the job, people playing guitar in office, everyone going out for lunch together, everyone felt like a good friend (and even after leaving are still good friends).

I preferred the second, I'm not sure which was more productive though...

I think the 2nd waa great few years but it probably wasn't sunstainable and I kinda understand an employer would prefer me to be a code creating robot rather than a human.
