Likely interview questions for this role
Written from this job description, not a generic list. Each one notes what the interviewer is really checking.
About your past
Tell me about an investigation where the evidence pointed somewhere you didn't expect. How did you handle it?
What they are checking: Whether they follow the evidence rather than a theory, which protects both the plan and innocent providers.
Tell me about a report you wrote that someone else had to act on. How did you make it clear and defensible?
What they are checking: Whether their written work stands alone for legal, compliance or law enforcement readers who were not in the case.
What would you do
You're reviewing medical records and the documentation is thin but not clearly false. How do you decide what to write in your findings?
What they are checking: Their ability to state only what the evidence supports and keep opinion out of the record.
You're carrying a dozen open cases with different priorities. How do you decide what gets your attention this week?
What they are checking: Their case management discipline, since dollar exposure and member harm should drive the order of work.
A colleague in another department asks you informally about a provider you're investigating. What do you say?
What they are checking: Whether they protect the confidentiality and integrity of an open investigation even with friendly coworkers.
About the work
Walk me through how you'd work a new referral alleging a provider is billing for services they never performed.
What they are checking: Whether they have a structured investigative method from intake through evidence gathering to a supported conclusion.
What patterns in claims data would make you suspect upcoding or unbundling?
What they are checking: Their working knowledge of common billing schemes and how they show up in the numbers.
How do you tell the difference between fraud, waste and abuse when you're looking at a provider's billing?
What they are checking: Whether they understand intent and pattern, which decides whether a case is education, recovery or a law enforcement referral.
How do you prepare for an interview with a provider or member who may be the subject of an investigation?
What they are checking: Whether they plan questions, stay neutral and document carefully so the interview holds up later.
Medicaid programs often require referrals to the state or a Medicaid Fraud Control Unit within set timelines. How do you keep track of those obligations?
What they are checking: Their awareness that regulatory and contractual reporting deadlines are part of the job, not an afterthought.
