The nice thing about large corporate environments is that you can hide and get away with doing very little. I was able to get large amounts of time allotted to small tasks, complete them in a day and slack off for the rest of the week, and still be rewarded for the "hard work". In my off time, I actually worked on automating some of my work so it would be quicker to do next time. Of course, no one knew this because it was not planned anywhere.
The pay is lower and you learn less and become rusty in everything else. As such, it wasn't a great environment for starting in, but would probably be a good environment to work the last few years in.
