There is a ramp up period for any new hire programmer, regardless of your expertise level; however, expectations are generally set based on your past work experience, what you claim to know and bring to the table day 1 and the complexity of the code base you're going to be working on and your role/position requirements within the team. Just be expected to show self initiative, be willing to dig and understand on your own but never hesitate to ask should you feel you've spent adequate time studying something but it doesn't click. Willingness to try and learn go a long way in the software industry, gaming or otherwise.
i think there are two schools:
- one is to consult sometimes, work and not talk to much
- second it ta talk almost everytime, share much opinions not only about the used language, codebase but even on the life questions. movies etc
I belong to the later, not only programming fellow is adequate to that, but some do and for me the second way of working (when i got some close fellows to talk with == good workplace, this is just much more fun; and the first is almost == bad workplace when i am more tired and sad
