I worked there for a little over a year as an AE. The benefits are very good...health, dental, etc. The 401k plan is matched at 50%, if I remember correctly, and vests after 3 years, which is about as good as it gets.
You will start with a base of 30k, commision is based upon the amount of assets you bring in, and bonuses depend on the number of clients you bring in and in what time frame.
For the commision, you receive 10% of the first year's fees that are assessed to each client you help acquire. These fees are based up the amount of assets under management. A million-dollar account is billed at 1.25% or $12,500 at the time the client signs on. You, in turn, receive 10% of this, or $1,250.
The bonuses, or "ramp-rates", depend on the amount of clients you help aquire throughout your first year. I don't remember the numbers exactly, but I believe that if you acquire 4 new clients within the first 2 months you receive $2500; 15 clients within the first 6 and you receive $5000; and 35 in the first year and you receive $7500. And yes, you can receive all the ramp-rates and, therefore, earn and extra 15k in bonuses.
If you clear all these ramp rates expect to earn 90-110k.
These are attainable, though certainly not easy, and the economy will play a large part in how many people feel comfortable moving that much money. I would say 1 in 20 AE's manages to do it.
As for the job itself, that's another story. Don't let your interviewers sell you on it. Make sure you have plenty of questions about what exactly it is that you'll be doing and what kind of training you will receive. You will NOT be learning a whole lot about finance like they will let you believe, and though they will make it a big point to tell you you won't be cold-calling, the leads for the most part are very far from warm.
Hope this helps.
