Pros
Depends on the management, usually older managers who have been there a while are very "Employee-centric" they will have your back. Many will work with your schedule. You have to be in the "right place, right time" for promotions. It isn't always based solely on your skill, but "who you know" really plays a big part. You can work on many different teams, and learn many different skills.
Cons
New managers are usually very "something to prove" and go above and beyond, even throwing people under the bus to show how "serious" they are about their position. A manager/supervisor etc. should not be someone who wants the position to earn more money, it should be someone who loves the department they are in and want nothing more than for everyone in the team to succeed. While there is a lot of favoritism, it is easy to get into the circle. Sometimes you get pulled into the "favorites" circle, without wanting to actually be a part of it. If you happen to get pulled in, you need to play ball. Be social, go out with the right people when they invite you out, etc. If you don't, some will see that that as being snubbed, and this can cost you your job. This can be very demanding of introverts who just want to go in, do their job and anything else they are tasked with, but don't really like going out for lunch or drinks.
