Pros
I had a wonderful manager, wonderful co-workers and a great workload/travel schedule. Quintiles is a company that values their employees and will give you some amazing perks. I believe them when they say that work/life balance is a priority for them. Being a CRA is very hard, but they really did try everything in their power to keep me as happy as possible.
Cons
The problem for me was that I was hired into the highest level that I could advance to in my current position and I was nowhere near ready for any of the other positions I could have advanced into. I dare say that I was hired above my experience/ability level. A transition in my direct manager near the beginning of my tenure there presented another challenge as I completed much of the wrong training before being corrected on what I should complete. It definitely delayed my ability to make a contribution to the company.
