Pros
I really liked most of the managers I worked with. I thought they were incredibly smart, willing to help, and overall nice people. I enjoyed the fellow analysts and I think if you are interested in valuation DP is a good place to get training and get exposure to different industries and different types of valuation. I've learned many skills and have become good at analyzing different data sets and financial modeling.
Cons
My biggest complaint, which you can see in many of the reviews, is that the company is paying below market rate. Also, if you are a top performer here and good at the job, your reward is more work until you are absolutely swamped. The delegation of work is with managers asking you to be on their projects, where you are expected to say yes. This leaves a few people in the office swamped with work, while others get to waltz out at 5 (those people will make the same or more than you). There are way to many bosses per analyst and everyone wants their project to be the #1 priority. Most of the issues have been exasperated since being acquired by Permira who is cutting any cost they can, without any regard to employee morale or view to the company. Which has caused a lot more turnover than usual as people do not seem too pleased with the company. Additionally, there seems to be a lack of transparency between pay/promotion across similar offices, and there is no flexibility in negotiating your salary.
