As an entry-level fraud investigator, you investigate fraud under the direction of experienced investigators, including credit card fraud, bank fraud, or fraudulent insurance claims. Your duties include collecting evidence to determine if fraud took place, reviewing transaction records or insurance claim information, and interviewing suspects and the bank, insurance, or credit card employees with whom they dealt. In cases in which fraud did take place, it is among your responsibilities to report your finding to senior investigators and make your gathered evidence available to relevant attorneys and prosecutors.
