There were 2 meetings. The first meeting was just to fill out paperwork and take an assessment. If you do good on the assessment then they call you in for a second meeting. The second meeting was the actual interview with the Owner and the Billing Dept Mgr in a 2-panel group interview.
The assessment had a bunch of different questions on it, namely, reading comprehension, math, analogies, spelling and comparing rows of similar looking data to see which one is different, but there were also some weird questions. None were software questions, and a lot of them were compare this image or chart and figure out what the correct data is suppose to be entered into the fields.
