Client Relationship Manager Interview Questions

I had a client at my former company who had 200+ employees enrolled with an incorrect medical rate, which meant they had incorrect deductions from their paycheck for 6 months before we found the error. I had to reach out to the client and let them know what had happened, how the error occurred, what we were doing to fix it, and what we were doing to be sure a similar issue does not occur in the future. I was open and honest with the client and told them we were to blame and apologized profusely. They were of course unhappy that it occurred, but they appreciated the honesty and that we were willing to do what was necessary to correct the issue quickly.
