Pros
Was a good company for many years with a solid reputation of quality contracts for the Feds and also a good work culture. Had a good leader in the COO and the owner seemed to care about the employees as people rather than just something that either made him money or cost him money. Then, he hired a hot shot executive to grow the company and abrasively pushed out the COO. You know the story after that.
Cons
I have to say that the many of the reviews here that are over the top positive appear to all be written by the same person. Same language use, same style. That kind of thing would not be beyond the new ECS. The company President and the Owner set about getting rich and it all became about growing as fast as possible at any cost. Some people like that kind of environment - generally the ambitious and the sycophantic. So that's what it became and the people who liked the former leadership left over time and what is left are the mean and the stuck.
