Pros
Many on the staff are talented designers that would be successful in most design firms.
Cons
The firm is really nothing more than a corporate raider who buys up smaller firms, pushes out the talent, absorbs their portfolios and backlog, then rinses and repeats by buying more firms every couple of years. They push the employees towards buying stock in the company under the guise of "employee ownership" but it is really just to be able to fund the purchase of more firms with no real ability to be an owner (common joke is the employees are told to "act like an owner" just don't think like one). This creates a culture clash and resentment, losing much of the talent that made the smaller firms successful. Many on the executive and leadership teams are passive aggressive and, in some cases, downright abusive. Their mentoring and employee management lacks authenticity and actual career guidance and often is checking a box rather than really living that goal. They are not supportive on employees who come with positive reputations outside in the industry. If a person has a national or international footprint and DLR did not "create it", they are often shunned from being in a spotlight (a major mistake IMO). If someone asked me to apply to DLR regardless of the discipline, and I knew then, the experience I and many others have had, it would be a definite no thanks. Watch their actions, as their words are snake oil.
