I think it is like any other place, where first impressions has a lot to do with it.
People want to know if you are a great worker.
Do you tend to follow or do you lead, as time passes people will learn how you work and vice-versa.
Some just want a trust worthy person that just goes with the flow, where as long as you look like you are working all is well. Similiar to following what the tenure workers do, unless you do procedures or tasks in a way that they learn to like.
Work culture and socializing with others, you will learn as you go, but it may seem like probation or a break-in period.
