Great people, great benefits, but little opportunity for advancement - Analyst AAMC Employee Review

If you are in an entry level or mid level position, it's difficult to advance to a higher level position unless another person leaves the company; there are over 40 units in the company, and each unit has a completely different vibe in terms of work ethic, friendliness, and conscientiousness. My particular unit is somewhat insular, somber, and very busy with work. People in my unit always work through lunch, eat at their desks, and generally don't interact with one another unless they have to (but when they do interact, it's always friendly).
