Pros
If it's the right fit for you, the money is fantastic. It takes diligence and hard work, and yes, the turnover is high, mostly because potential employees have unrealistic expectations of what they are getting into. It's important to understand that this is a sales culture and you will be managed accordingly. You need to be comfortable responding to metrics, proving yourself, and having a continual drive to succeed. Excellent place for a self-motivated individual who likes writing his/her own paycheck. At the management level, especially the management roles that also carry production responsibilities, it's an environment where you will be held accountable for your contribution to the bigger picture.
Cons
The hours are long and it can be difficult to maintain a work/life balance, especially if your workday is bookended by a long commute or if you have management responsibilities. The benefits do not include tuition reimbursement (as if you'd have time to go to school anyway).
