Do you understand our primary customer base at UPS?

Part of your research before going into an interview should include the demographic that UPS is trying to reach. Perhaps their customer base is made up primarily of small business owners. Or, maybe they focus only on custom business solutions for large-scale companies. Discuss with the interviewer your understanding of the customer base at the UPS location where you are interviewing, and talk about how your experience will benefit them should they choose to hire you.
