Pros
This is the only place I worked where there are very few pros. If I can think of any I will update my response. I've worked at other staffing agencies and would recommend to keep looking after coming across Pyramid Consulting Group.
Cons
The company is unorganized and there is very high turnover. One of the worst parts is that there's no HR so there is no one to protect you. If you think you're company on for a certain position, don't be fooled. You will find yourself juggling tasks from multiple departments. Their reasoning is this happens because it's a small company and everyone has to chip in where they can, but frankly, they just take advantage of their employees. Also, the benefits program is the worst I've ever seen and the CEO is clueless.
