Pros
Culture is amazing, you can speak with any one in the company no matter their level very easily. There is high transparency with management/when it comes to achieving goals. The road map for sucess is clearly defined. It is a great entry level job, and you can learn alot about a variety of industries by working in staffing. There is a lot of focus placed on continuing education, training, and philanthropy within the company. These things help you improve as a person. The Austin office in particular has great leadership, sense of culture, and works with very interesting clients.
Cons
The staffing industry has alot of ups and downs, you need to have thick skin and be able to move past road bumps quickly. If money is your biggest motivator it will be easy to suceed, but if it isn't it may be more difficult to remain motivated over time.
