Pros
DRT has a very high quality product, and does cutting edge, high quality work. The technical team is strong, nearly everyone is smart and hardworking, and you learn a lot from working with people with great ideas.
Cons
Upper management provides no leadership. Endless planning committees are formed to address problems, and no progress is made on pressing problems for years. The project management culture stifles innovation, with even small technical tasks being subjected to a multi-month approval process that prevent engineers from responding to customer problems, and "priority 1" projects can meander for months or even years waiting trying to pass through artificial project gates. This has resulted in an increasingly apathetic work culture, with engineers and even low level managers excited about the technical content of their work, but feeling helpless to make anything better for the company or for customers.
