PCMI Services interview questions

I went through a screening interview, an onsite interview with the COO, and an onsite CEO. The first two were fine. In the third interview, the CEO asked about my experience with specific accounting and billing systems. My resume doesn't claim I have that bit do I state that in the previous interviews. The CEO was looking for something specific. Additionally, he cut me off when I I tried to answer one of his questions. They wasted my time.

The hiring process is as simple as they come. You fill out the application online, they email a questionnaire to your references, you watch a few videos online, you go in to their office pay for a background check (fingerprints), once that is received you pay for a substitute teaching permit and you are off to teaching.
