Pros
If they have contracts/projects with a client, then it is a good way to learn about that company's internal processes and build your network. You're gonna need it!
Cons
This is a staffing company, NOT a consulting firm!! They will give you the feeling that you are joining an elite team of consultants working on unique projects at fortune 500 corporations. However, this is just a way for them to lure you in. There are some good people working for them, and most of them are there while they are "actively" looking for a REAL job elsewhere. Most of the employees are based out of Costa Rica, i.e. cheaper resources and you get what you pay for. Intertec is trying to compete with other IT consulting firms from India, and failing miserably. P.S: The employee benefit plan is worst than what you would get when working at a minimum wage job.
