Datamatics does their best to place the right people in the right jobs, and if you're willing to just take ANY job you won't be satisfied. Explaining who you are and what your needs are is just as important as an employer explaining what the job description is. Datamatics can't help place IT positions if potential contractors don't know what they are looking for.
Datamatics is just like any other placement facility. You have to work with them on your needs to find a good fit.
