Pros
You are exposed to a large network of very interesting and influential people. Co-workers for the most part are smart and always willing to help one another. Program is great for entrepreneurs, but terrible for employees.
Cons
Most of the negative reviews found on glassdoor are true, at the end of the day they really are just a glorified incubator/accelerator. Turn over rate is high for a reason because they ask for Master's/PhD candidates, even though the majority of work is more akin to a coordinator. Minimum education required should be college/university. If you get an offer from them you should probably turn them down unless you really have nothing else going for you. Much like how the Central Bank is a lender of last resort, CDL is an employer of last resort. If you stay their for too long you will be pigeon holed and finding work elsewhere would be quite difficult.
