I am graduating this year from university (United States), and have a job offer at a large scale software company. I was an intern at this company this past summer and I was not a huge fan of being a part of my team. They are all great people individually, but the team environment left a lot to desire (think: nobody eats lunch together, team mentality is to get in, do work, go home).
I have friends who interned / work at this company, and they have very vibrant team environments that sound like a bunch of friends working together. In fact, the company is pushing the culture towards this paradigm. I just happened to land in a team that is a little behind the times.
I have already signed the offer because offer deadlines are brutal, but I have been dreading going back to that team ever since. I have been thinking about asking the HR if I can move teams before starting at the company next year. The problem is that the offer is tied to my team specifically.
Question: if I email HR about a change of team request, will my manager know?
