Very typical interview questions associated with customer service. Keep in mind that this role is a customer facing position, and, as such, they are looking for a customer service specialist above any biomedical abilities. "give me a time that you couldn't perform your job; what did you do? How did you interact with the customer? What would you do if they were visibly upset? etc
During my phone-only interview with Craig "C" - I was underhandedly asked a question with a "friendly" tone which alluded to organized labor. It was designed to gauge whether or not I was in favor of labor unions. The question was phrased as "now, just as something a bit off topic, do you feel that a person working the same job but not doing equal work should be paid the same as the person in the same position who is doing more work?"
