Do you know any of our customers?
The interviewer is interested in finding out if you know any of the company's clients. It is beneficial to the company if you have existing relationships with any of their customers because this will make it easier for you to introduce and/or sell their products to them. If you already have connections within the industry, definitely name drop and let the interviewer know. If you don't, indicate that you are working on building up your industry network and understand the importance of doing so.
