Welcoming questions

  1. Can you tell us about yourself and what drew you to internal audit?
  2. Which audit engagement are you most proud of, and what changed in the business because of it?

Role-specific / technical competencies

  1. How do you build a risk-based audit plan? Walk us through how you would assess and rank our audit universe.
  2. Describe your approach to testing the design versus the operating effectiveness of a control.
  3. How do you document work papers so that another auditor could re-perform your testing?
  4. What is your experience with COSO, SOX, or other control frameworks, and how have you applied them?
  5. How have you used data analytics in audit testing, and where did it change your conclusions?

Behavioural & culture fit

  1. Tell us about a time management pushed back hard on one of your findings. How did you handle it?
  2. Describe a situation where you had to stay objective despite pressure from a senior colleague or a friendly relationship.
  3. How do you build cooperation with teams that see audit as the enemy?

Problem-solving / case

  1. During an audit you notice expense approvals that look like a manager approving their own reimbursements through a proxy. What are your next steps?
  2. You have four weeks and one junior auditor to review our procurement process for the first time. How do you scope and execute the audit?
  3. A finding you reported last year was marked remediated, but you suspect the fix is cosmetic. How do you verify it and what do you do if you are right?
