A very neutral opinions - Anonymous employee Survey.com Employee Review

great pay, flexible hours, better you do the better the pay gets, some jobs pay bonus and travel pay as well

If you mess up at all you get downgraded and no more bonus high pay jobs

You can pick your assignments.

The company will find invalid reasons not to pay for completed assignments, with the expectation that you will not fight it. I have completed at least 2 assignments that they did not properly pay the agreed upon rate, or deducted hours that were accounted for.
