Cons
They will promise you opportunities that don't exist. The company they contract you to will promise you work that you will not be assigned. I was a Java Consultant with a masters degree in Math and certificate in full stack and I was shoved into a manual testing position that required zero coding and constantly dangled automation in front of my face. When I was asked to look at Selenium, I studied it in some of the copious amounts of downtime i had and was reprimanded during the next meeting for 'wasting company time'. I moved from Texas to New Jersey for my first position. After contracts with the company were terminated, I was pulled off my assignment only to be abruptly fired for "lack of geoflexibility" despite willingness to move to several places they do business including NYC and even Denver. There is no accountability from them as the only response they give is "the decision is final". There is no way to appeal a blatant lie. Their company has no integrity and side with business majors over people that know how chemicals and physics and electrical components work just seem like bad life decisions. They will say you can reapply but they won't hire you. They'd full of it at every angle.
