There is one positive thing I experienced in the position of Assistant Manager: I learned that in sales, you have to be thick-skinned to face your customers.
Outside of this, I felt it was dishonest that they posted the position as a management position, when it was nothing but a cold-calling sales job. I came out of college with an MBA, and had experience managing people, but wasn't managing anyone in this position. When Center Managers or Regional managers make mistakes, they blame them on the people beneath them to their superiors, rather than fix the actual problem.
The strategy of growth for this company was recklessly aggressive, and they make expensive mistakes trying to be the largest education company in California in a short period of time.
