Pros: good entry point.
Cons: sometimes, for some people, a lack of a career path beyond an entry point.
If you are a person who is looking for a good entry point into Clinical Research, then Hill Top is a good place to start.
The company gives adequate training in GCP and GMP and ICH guidelines and allows for room to make a few mistakes along the way and, yet, you'll move forward with good corrective action and you can develop somewhat within the ranks of this company.
Your development, within your standing job duties, can be almost limitless.
The facilities and personnel I have visited have all be casual and friendly and always willing to answer your questions...and this is great.
