Pros: you'll get a variety of clinical experiences.
Cons: the pace is unsustainable.
This is a good place to work if you don't need to work or it's a second family income. If you're single, forget it. You won't be able to make enough money unless you want to take on two roommates or live with your parents.
Therapist contracts are Base Pay + FFS. You'll get a small base salary that changes quarterly, based on your previous quarter's productivity level. In order to make their "estimated income" for a liveable wage, you will have to see 30-35 clients per week. That means scheduling upwards of 45 clients per week (to account for cancellations/no-shows). It's exhausting and you won't have a life outside of the office.
Management is corporate, cut-throat and ultra-conservative. It's a privately-owned, for-profit organization. You'll definitely feel replaceable. Lots of focus on productivity, oversight, compliance and legal liability. (More than other organizations.) Your productivity is measured in "units", not clients, consumers or people. The general atmosphere is dehumanizing.
However, if you want to jump head first into the fire and be exposed to every conceivable type of client and diagnosis, this is the place to do it. Your clinical skills will be honed. Just don't plan on operating at that pace for long. You'll burn out. Use it as a stepping stone in your career.
