    Easy Interview


    I applied through a staffing agency. I interviewed at Quest Diagnostics.


    The interview was quick and easy. I interviewed with two supervisors. The interview lasted about 15 minutes. None of the questions were difficult. They want to make sure you are good with Microsoft Excel and Outlook.
