I too have recently started a new job. I had a phone screen with the hiring manager, then met with him for a two-hour 1-on-1 interview. Some time later I was given the offer and accepted it.

I never met any of my future team members. I asked the hiring manager during the interview to introduce me to the team, but he said this wasn't going to be necessary.

Now, a few months into the job, I must say that I've never worked on any team composed of such antisocial people. Pretty much no one here communicates effectively. Cliques are demarcated along racial lines; there Chinese and Indian groups don't really talk to each other, and don't "accept new members" that don't speak their language.

This is the loneliest place I'd ever worked. What's surprising is that I never thought I could be so lonely at work of all places.

So, lesson learned: if you aren't allowed to do a meet-and-greet with the team before accepting an offer, don't even think about taking it!
