I bet you'll learn a helluva lot more than that.
I'm not sure why there's such a negative undercurrent in this forum regarding larger organizations. Maybe negative experiences, maybe just heresay. Of course, the culture will be very different from a startup. But there's lots of good stuff, too.
I've worked in quite a few large companies, but now mostly small ones. Invariably, one of my small clients runs into an issue that none of their 30 employees has ever encountered before. So they try to figure it out. Until I say, "Here's how you do that..." Am I a genius? No. I've just seen the exact same thing handled very well in several large companies. Also (invariably), one of my small clients has to hire a manager of <you name it> who has vast experience in a large company. They always bring solutions to lots of problems that no one has ever imagined there.
Don't discount a large organization. It may be weighed down by its size, but you'll be able to witness LOTS of interesting stuff that you'll see nowhere else.
