The short answer: auditor interviews test your technical understanding (the audit process, risk, internal controls, materiality, sampling), your judgment and skepticism, your ethics and independence, and how you communicate findings, especially when people push back. Entry-level interviews focus on fundamentals, motivation and attitude; experienced interviews go deeper into engagements you’ve run, issues you found and how you handled them. Below are the common questions with short answers, the behavioral questions to prepare for, and what the job pays.
What the job involves
The U.S. Bureau of Labor Statistics describes accountants and auditors as people who “prepare and examine financial records, identify potential areas of opportunity and risk, and provide solutions for businesses and individuals.” It distinguishes internal auditors, who work for the organization they audit and look for ways to reduce waste, fraud and financial risk; external auditors, who check an organization’s financial statements and controls and report to investors and authorities; and IT auditors, who review controls over information systems. The median pay for accountants and auditors was $83,680 in May 2025, and employment is projected to grow 5% from 2025 to 2035, with about 115,300 openings a year.
Motivation questions
“Why audit?”
Be specific: what you enjoy (understanding how businesses work, finding problems, being trusted to give an independent view) and where you want it to lead. “I like seeing how a business really works from the inside, and audit lets me do that across many companies early in my career while building a strong technical base.”
“Internal or external audit: why this one?”
External audit offers variety across clients and a strong foundation; internal audit offers depth in one organization and a closer link to improving operations. Show you understand the difference.
Technical questions
“Walk me through the audit process.”
Planning (understanding the business and assessing risk), testing controls, substantive testing of balances and transactions, evaluating findings, and reporting. Emphasize that the work is driven by risk.
“What is audit risk?”
The risk that the auditor gives an inappropriate opinion on financial statements that are materially misstated. It’s commonly broken into inherent risk, control risk and detection risk; the auditor can only control detection risk, through the nature, timing and extent of testing.
“What is materiality?”
The threshold above which a misstatement, alone or combined with others, could influence the decisions of users of the financial statements. It guides how much testing you do and which findings matter.
“What’s the difference between a test of controls and a substantive test?”
A test of controls checks whether a control is designed well and works in practice (for example, whether purchase orders over a limit are actually approved). A substantive test checks the numbers themselves (for example, confirming receivable balances with customers).
“How do you choose a sample?”
Based on the risk, the population and the objective, using statistical or non-statistical methods. Larger samples for higher risk; targeted selection for large or unusual items.
“What are common internal control weaknesses?”
Lack of segregation of duties, missing approvals, poor reconciliations, weak access controls over systems, and manual processes without review.
“What red flags suggest fraud?”
Unusual journal entries (round numbers, posted at period end or by senior staff), transactions outside normal processes, reluctance to provide documents, and lifestyle or behavior changes. Know that the response is to escalate according to procedures, not to investigate alone.
“What is an IT general control?”
A control over the IT environment that supports reliable processing, such as access management, change management and backups.
Ethics and independence
“What does independence mean for an auditor?”
Being free from relationships or interests that would compromise, or appear to compromise, objectivity, such as financial interests in a client or close relationships with client management.
“What would you do if a manager asked you to ignore an issue?”
Stay polite but firm: document the issue, explain why it matters, and escalate through the proper channels. Your integrity is the job.
Behavioral questions
- Tell me about a time you found an error or problem others had missed. See solving a complex problem.
- Tell me about a time you had to deliver bad news to a client or manager.
- Tell me about a time someone pushed back on your findings. See handling conflict.
- Tell me about a time you managed several deadlines in a busy season. See how do you handle stress.
- Tell me about a time you made a mistake in your work.
Use the STAR method, and show your attention to detail and professional skepticism in the action you describe.
