The culture has vastly changed. I'd advise (studying or not) if you have been with the company for more than 2 years to think about what you really want from the company it is easy to get comfortable and 98% of the time you meet and work with incredible people but don't let that stifle the other dimensions to your professional self. Development is much harder to see happen now and progression is a much longer process than it was in the past, this and your experience is so dependent on where you are.
It's a great job with loving people and good fun. Lots of hard work, you are on your feet all day and you give a lot of your emotional energy to your role aswell. Don't let the fun get in the way of making sure you get training to work beyond the role you start in.
