I think this is all normal. Any big company that's been around for a while has a lot of internal infrastructure that's poorly documented. Often, in the first few months of a new job, when I go to a meeting, not only can't I contribute anything, I don't even know what the words mean.

Perhaps you can befriend someone else who started around the same time and talk to them, I bet they're feeling something similar.

Anyway, I do think what you're being too hard on yourself. You're probably developing meta-knowledge: you may not know the details of the code & tools, but you're learning the underlying concepts and who to talk to about what.

You should also be able to ask your manager for feedback on how you've been coming up to speed, or ask what's typical for people new to the job.

Three to 6 months is often stated as a ramp up time, so I wouldn't be too worried about your 2nd month.

Also, there will be a lot of code & tools you never learn well. That's ok, its not about the stuff you don't know, it's about the stuff you do know.
