Eight Senior Internal Auditor interview questions, and what the interviewer is thinking

1. Why internal audit, and how do you stay independent while building a good working relationship with the business?

Why they ask: They want to see you can balance challenge with partnership, which is the central tension of the job.

2. How do you plan and scope a risk-based internal audit, and where does assurance mapping fit?

Why they ask: Planning quality determines whether the audit adds value, and they want a structured method.

3. How do you structure an audit finding and how do you make sure the recommended actions are effective?

Why they ask: Report writing and follow-through are where internal audit makes its impact.

4. How do you decide whether a control is well designed, and how do you then test whether it operated effectively?

Why they ask: This is the basis of control testing, and they want a clear approach.

5. How would internal audit give assurance over a company's readiness for the failure to prevent fraud offence under the Economic Crime and Corporate Transparency Act?

Why they ask: This is a current regulatory development and they want to see you can respond to new risk.

6. Talk me through how you would plan and carry out an internal audit of the procure-to-pay process.

Why they ask: It is a typical audit assignment, and they want to see practical process knowledge.

7. Management have not implemented several agreed high-risk actions, and the due dates have passed twice. What do you do?

Why they ask: Follow-through shows the strength of an internal audit function, and they want to see appropriate escalation.

8. Tell me about an audit where your recommendation added real value to the organisation.

Why they ask: They want evidence that you go beyond compliance checking and improve outcomes.

A sample answer to question 1

Why internal audit, and how do you stay independent while building a good working relationship with the business?

I chose internal audit because it lets me look at the whole organisation and help improve how it is run, rather than focusing on the numbers alone. The difficulty is balancing independence and being useful. I believe independence is protected by structure, such as reporting functionally to the audit committee, and by behaviour, such as not taking part in designing or running controls I might later audit, and being clear about what I will and will not do. Within that, I try to be a constructive partner: understanding the business before I arrive, explaining my approach upfront, sharing emerging findings early, so there are no surprises, and recommending actions that are practical. I treat the audit as joint problem solving. The relationships that I build mean managers share issues with me earlier, which improves the quality of the assurance I can provide to the audit committee.

Common mistake to avoid: Presenting audit as policing; claiming independence does not matter if relationships are good
