Pros
Fair pay, reasonable benefits, for the most part really good people. A good client list who are as loyal as any in this time of "low cost wins all." For the most part this is a good company with good rank and file staff who take pride in delivering a great service. The company tries hard to provide a decent work/life balance for the staff, promote good health, and get people together for little social events. The projects won are usually interesting and sometimes challenging, although those are getting harder and harder to come by.
Cons
DEA used to have the reputation of being cutting edge, willing to invest in new technology, ideas, and take some reasonable risks. Since the recession, there has been little willingness to move forward with new approaches or technology or to improve IT issues, equipment, or to embrace the ideas of the newer generation of engineers. The idea of growth thorough acquisition has been lackluster at best. DEA is very proud of its cultural drivers, but like so many things they have a hard time living up to those ideals in practice. Marketing has been gutted and there has been a steady exodus of valuable institutional knowledge.
