The work is only 1 part of the job. You have to train yourself and learn how to be socially competent if you want to be successful. This does NOT mean you need to be the life of the party or friends with everybody, but you DO need to learn how to be friendly and social… that goes for both the audit team and the client.
Start with very basic questions when you're talking with people informally (lunch, coffee breaks, etc.) such as:
– How was your weekend?
– Any vacation plans for later this year?
– Weather (rain sucks, sun is awesome, snow is ehh, and so on)
– Hobbies
– Favorite tv shows or movies (work appropriate)
Again, you don't have to know everything, but don't be that silent awkward person at lunch or in the audit room. You won't be hated, but you also will have trouble fitting in. You won't get fired for that, so don't worry about that.
Avoid “taboo” topics (different in different cultures, so be aware of that). For example, in the US, politics are mostly taboo in a professional setting. Every person is different, so there's no behavior that will work for everyone. Just work on at least being kind and professional at work and that's a great start. Over time, you can work on trying to improve social skills.
Don't change yourself just to fit in. If you feel that you would be doing something you feel is immoral or that goes against what you want, then just realize that the culture is not for everyone. Many people (myself included) left the big 4 due to a mismatch between how they operate and how the firm works.
Is there more to the story? Do you feel the team is excluding you or something more than just what you said above?
