Invisible Technologies Customer Service Agent interview questions

I received an invitation and as I usually do, I joined a couple of minutes before to be on time. Recruiter was interviewing another candidate which gave me the impression he was doing flash interviews in a row. Our interaction lasted 15 minutes and I was asked a few questions, the interaction was focused on the role duties. They advertise only $5 to 7/hour rate, this is not true, they offer salary based on performance/ sucessful calls.
