Pros
The people there are great. It can be a bit of a learning curve if you're walking into a sales situation for the first time but other than that it's great. As with any sales job, it has its stressing moments. But, they pay well and they lead the market in advertising, so that's always a plus.
Kontras
The biggest issue may have to be the amount of work they can put on you at one time. It just gets to a point that there just aren't enough hours in the day and as they'll put it, "this isn't a normal 9-5 job"
