I agree with this, and would add: ask the questions now about what does this mean, what do you mean, how does that work here etc... If you wait 6 months and still don't understand because you didn't ask questions, then you will run into problems and people will start pressuring you or isolating you. When you are new, everyone expects those questions and are generally fairly happy to help, and in really large companies it can take a year to become truly competent in the solution. But if you aren't asking questions or aren't understanding, raising your hand about it etc, they will assume you get it and move on. Then you will be judged like you know all the material when you really don't and that is hard to recover from.

Big teams have their own challenges, but in general, you should likely have a small immediate team that is your focus. So while you need to figure things out, don't freak out about things 3 teams over that you don't understand right now. It is really common in large teams that your area of expertise will be focused around what your immediate team works on, and no one expects you to understand all the other team's work. What makes people "invaluable" is that they push to learn the "entire" system (or as much as possible) from each of the teams, which means they become a wealth of knowledge even if they've been there less time than others. This used to be my trick as a freelancer that led to me transitioning to a true consultant when I built my first consultancy. I'd go into large teams, do the job I was hired for but learn the entire system because I wouldn't stop asking questions, exploring etc. Then within 6-9 months many times I knew more than people that had been in the company for years, only because they stayed in their cube and did what tasks they were assigned but didn't ask questions and explore.
