Pros
The training for the Series 6 is excellent; the instructors are very helpful and knowledgeable. The Windsor building is relatively new, and the cafeteria is pretty good although expensive. You get a good chunk of PTO to start out with, although you will rarely get the approval to take it. There's plenty of parking and it's free.
Cons
The ING Call Center is the most hostile work environment I've ever experienced. There is no support from supervisors, who actually encourage the "sink or swim" office mentality. Reps are expected to make referrals and push sales for no incentive or commission. The obsession with call metrics is disturbing- supervisors monitor every email you send, every minute spent in the restroom, every moment you spend off the phone will be questioned.
