I spent the first 15 years of my career as follows: 3 years in small companies outside the bay area 10 years in bay area startups ~2 years in bay area big corporations I can say the following. The transition from startup to big company was really tough. Part of this was because I was used to being "the guy" for such a wide range of things. At big corporations, these roles are divvied up into 5-10-15 different roles. This is both good and bad. On the plus side, I can relate somewhat intelligently to colleagues across a very wide range of roles. On the minus side, the colleagues all (rightfully) feel their areas are their domain and don't typically recognize expertise coming from outside their team. This knowledge with lack of credibility was hard to reconcile until I fully realized what was going on.
