Pros
There are no pros whatsoever. Absolutely none. That is, unless you enjoy being treated like dirt by unethical sleazers and then not getting paid for your efforts.
Cons
Sprim is perhaps the shadiest company on the planet, no make that the universe. The company leadership is defined by lies, corruption, and deceipt...both to their employers and well as clients. I know, I worked there for several years. If you are a current employee, let me guess, you haven't been paid in months, but they continue to lead you on by the promise of the next big contract (which never comes). if you're a prospective employee, you hear promises of wonderful teams and projects, only to be disappointed by corruption. If you are a client, you are being snowed, plain and simple. in all liklihood, your data are being made up. If you're running a clinical trial, have you ever wondered why your data are so positive? It's because the data are not real!
