All hiring managers expect certain things from their staffing firm; good customer service and quality candidates fast. Too often that is where it stops – both the expectations and what many staffing firms are able to deliver. 

When you are being interviewed, you are NOT in control of the situation.  The only time you gain control is when you ask questions.
 
QUESTIONS CAN REVEAL THE FOLLOWING:
* Important information about your credentials that did not come up in the interview
* The priorities of the person interviewing you
* More detail about the opportunity
* Where they are in the hiring process
* If you will be considered for this opportunity
