Avoid discussing that this never happens for you. Do not share that you don't learn anything from them and that you just move on to the next call or meeting.

Share an example of a client that you lost. When an interviewer says to "tell me about" then that usually means they want an example from your previous work experience. End with what you learned from it and how you have used that lesson with your other clients.

"I lost a client in my current role due to my lack of follow-up and follow-through. I had several calls with him and he seemed very impressed with the product and service. I sold him the product which involved a three-month cancellation period if he didn't like it. I got caught up in taking on too large of a book of business due to the growth I was having and got behind on my follow-ups with recent clients who purchased. He ended up canceling after the three-month period and I realized quickly that I needed to scale back my book of business. I spoke to my manager and we found a good number of clients that worked well for me in order to be able to handle every part of my role."
