Red flags
- Would change vendor bank details based on an email alone
- Willing to skip approvals when asked by senior staff
- No method for preventing duplicate payments
- Careless data entry habits
Questions not to ask
- Have you ever been arrested for theft? — arrest records generally should not be used, and many states and cities restrict criminal history questions; check your state's rules
- Do you have children or plan to? — family status and pregnancy discrimination risk
- What is your credit score? — many states and cities restrict credit-based screening, and federal law requires consent and notices
- How old are you? — age discrimination risk
