Pros
You can make a ton of money and if you get the right manager, you can little/no oversight. Vendors provide a ton of perks, free concerts, ballgames, a happy hour every night of the week, free lunches, etc. There are a decent amount of good people left working there
Cons
They've cut pay every single year since I started in 2004. Literally every single year. And account managers have the same base salary($25k) they did as long as anybody I know that works there can remember(15+ years). They have a focused effort to devalue the role of account manager and have consistently been stepping down compensation more drastically in recent years. The caliber of people they've hired the last five years is really, really bad, so a lot of your coworkers are there because nobody else will hire them and they're willing to work for $25k. The fact that they've hired a lot of terrible people recently has also had a bad effect on morale. It's never been lower since I started. Even people making top dollar hate their jobs. Also there is zero career path. If you dream of being a sales manager, well keep dreaming--last I heard that job starts out at an amazing $45k base salary.
