Demonstrate to the interviewer that you can acknowledge when you don't know something instead of making it up on the fly and commit to finding that answer and following up with the customer timely. Give an example of how you self-help and track down information or how you've found the appropriate person to ask. Telling a customer, "I don't know," or "that's not my department," is never appropriate, and the interviewer wants to learn more about your customer service skills and problem-solving approach.

"As a newer employee in sales, I would have a lot to learn, so I'm sure I will run into a situation where I cannot immediately answer a customer or client's question. I would be transparent and let them know I would research the answer and get back to them as soon as I could. I would never make up an answer and would try to self-help with my available resources, and if I could not locate the answer timely, I would reach out to a colleague or manager to assist."

"In a client-facing role like this, the customer experience is always my top priority, so if they asked a question to which I didn't know the answer, I would reassure them that I would find the answer for them and help them resolve the issue. If I knew it would take me some time to track down the answer, I would ask them if they had time to hold while I looked, and if they didn't, I would take their information down and get back to them timely. Follow-up is also important to me, and if I committed to finding an answer and getting back to them, I would ensure that I did."

"Working in tech support, I often get questions from customers related to other areas that I'm unfamiliar with. I know that being transferred a bunch of times is annoying to customers, so I take the time to make sure I find the appropriate person to handle their questions before transferring. Prior to transferring, I give the customer the direct line they need and upon transferring their call to the right person, I always wait until that employee comes on the line before excusing myself."
