If you suspect occupational fraud, you’ll want to engage financial and legal advisors to handle the investigation. But, before they arrive, you may need to perform interviews to help resolve doubts and obtain information. Aim for informal conversations and remain calm and nonthreatening. If you believe someone is withholding information, try asking more detailed questions. And if someone seems to be lying, request clarification. Never make threats or promises to encourage an employee to change a statement or confess.
