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 audit issue you found. How did you get to the root cause instead of just the symptom?
What they are checking: Whether they dig past the failed control to why it failed, which is what makes corrective actions stick.
Tell me about a time you led a meeting with people more senior than you. How did you keep it on track?
What they are checking: Comfort running opening and closing meetings with managers, which the posting requires.
What would you do
Management disagrees with a finding you're confident about. How do you handle the conversation?
What they are checking: Holding a well-supported position professionally while staying open to facts they may have missed.
You're halfway through fieldwork and realize the engagement will run over the budgeted hours. What do you do?
What they are checking: Whether they raise schedule risk early and adjust scope wisely instead of rushing or going silent.
How would you follow up to make sure management actually carries out a corrective action plan?
What they are checking: Whether they verify remediation with evidence instead of accepting a status update at face value.
About the work
Walk me through how you document a process walkthrough and identify the key controls in it.
What they are checking: Hands-on control identification, which the posting lists as a required skill for this auditor role.
What makes a workpaper meet Institute of Internal Auditors standards? What do reviewers usually push back on?
What they are checking: Whether their workpapers can stand on their own so another auditor reaches the same conclusion.
How would you test the operating effectiveness of a control, and how do you decide on a sample size?
What they are checking: Core testing knowledge, including the difference between design and operating effectiveness.
How would you write an audit finding so a busy executive understands the risk in a minute?
What they are checking: Clear writing with condition, criteria, cause and effect, so findings lead to action instead of confusion.
What's the difference between an audit and a consulting engagement for you, and how does your approach change?
What they are checking: Whether they understand independence and the different role an auditor plays when advising rather than assuring.
