Describe a time where you tried but couldn't make a sale.

"When I worked in sales in another role, I was tasked with trying to sell our policies to individuals at a small company in the city. I was able to make sales to the majority of individuals, but one customer was not happy with our coverage. I had many conversations with this customer, trying to find a policy that would work for them and even working with my supervisor to try and customize a policy for them. Despite these efforts, they did not purchase a policy from us. I was initially really discouraged, but after discussing with my supervisor at the time, I realized that I had done all I could to make the sale and was reminded that sometimes, the sale just isn't going to happen and that's ok. After this, I continued to remind myself after every failed sale that sometimes it isn't about your ability to sell, but that sometimes, a customer has another idea or product that is a better fit, but if I am confident that I did all I could, it is still a success."
