Focus on an ethical situation related to your position as a Fraud Investigator. If you do not have prior experience as a Fraud Investigator, use an example from school or another job.

Avoid saying you have never had your ethics tested. Most people have had at least one situation that tested their ethics. Maybe you witnessed someone cheating or stealing. The interviewer wants to hear that you step up and do not let someone get away with unethical behavior.

"Yes, I had my ethics tested in a previous job as a Fraud Investigator. I interviewed an employee who was suspected of embezzling money from the company. She knew I had information proving she was taking money, and she offered me a bribe to hide the evidence. She offered me a large amount of money, but I politely told her that what she was offering was unethical and illegal. In the end, she was charged and convicted of embezzlement."
