Avantages
As a former contractor working for them, I have no reason to recommend working for MODIS.
Inconvénients
Their margins are high; for the position I was contracted out for it was almost 80%. They will promise you increases in wages and then not deliver. They messed up my Federal Tax withholding resulting in an extended period of time of my having to play "catch up". Toward the end of my contract, I found out that MODIS had reimbursed the client part of MODIS' fees while I had paid for a year's living expenses (in the client city where I was working) out of my own pocket. Also, when I advised my recruiter that I was not being paid my earned and due overtime because the time-reporting system at the client site was locked down at 40 hours per week in violation of Federal Wage & Hour Rules, MODIS did nothing.
