Pros
If you are in desperate need for a job these people are willing to help you sell your soul to the devil. The pay is ok. They also pay for travel to client site/hotel for 2 weeks/an apartment (completely paid for) to stay when you first join to help get you on a contract(this is a consulting firm). They helped me to get on a project very quickly.
Cons
Where to begin? Noncompete Clause, Reimbursement for Training in the tune of 20k if you quit, No benefits, Lies Lies and more Lies. They will change your resume and put lies in it. They impersonate you and tell their companies that you have years of experiences and worked at companies that you never have worked for. They will intimidate you into lying to their "clients" [they just spam Indeed with their deceitfully prepared resume] to get a project. They also completely changed the job type/title/duration. What they offer (other then the pay) is a lie. Do not work for these crooks.
