The co-workers and work environment are great and I got to meet a lot of great people.
I was in advertising sales. The problem is, the senior & mid-level reps already have their hands in all the agencies (that basically just send them clients). Entry-level reps are left with small accounts; with such a low commission, it's hard to deal make it up. There is a very high turnaround rate.
There seems to be no advancement. If you're a senior or mid level rep and bringing in agency jobs, they won't promote you. There are people that have been there for so many years and are still in the same position.
Management - they are cool to hang out with as friends but as managers, they are terrible. They manage out of fear, which is the worst way to manage. Try managing out of support and encouragement and see how much better your employees perform!
