Auditor interview questions

A financial statement audit provides an independent opinion on whether the statements are fairly presented under the applicable reporting framework.

• The auditor looks for material misstatements rather than guaranteeing that every number is exact.
• The opinion increases confidence for users such as investors, lenders, and regulators.
• Management still prepares the statements and remains responsible for their content.

A financial statement audit moves from acceptance and planning through risk assessment, testing, completion, and reporting.

• Acceptance includes considering independence, management integrity, and whether the firm can perform the engagement.
• Planning and risk assessment identify material areas and determine the nature, timing, and extent of procedures.
• Testing gathers evidence through controls work and substantive procedures.
• Completion covers final evaluations, subsequent events, going concern, and the audit opinion.

Management prepares the financial statements and internal controls, while the auditor independently examines the statements and expresses an opinion.

• Management selects accounting policies, makes estimates, and maintains records supporting reported amounts.
• Management designs and operates controls intended to prevent or detect material misstatements.
• The auditor assesses risk and obtains sufficient appropriate evidence without taking over management decisions.

An unmodified opinion communicates that the financial statements are fairly presented, in all material respects, under the applicable framework.

• It is based on sufficient appropriate evidence gathered during the audit.
• It provides reasonable assurance, not a guarantee that the statements contain no error or fraud.
• The wording refers to the statements as a whole rather than certifying each account separately.

Financial statement assertions are management's explicit or implied claims about transactions, balances, and disclosures.

• Auditors use assertions to translate a broad account risk into a specific possible misstatement.
• Assertions guide which procedure is suitable, such as vouching an asset for existence or tracing source records for completeness.
• The relevant assertion can differ by account, so the same procedure does not address every risk.

Transaction assertions commonly include occurrence, completeness, accuracy, cutoff, and classification.

• Occurrence asks whether recorded transactions actually happened and relate to the entity.
• Completeness asks whether every transaction that should be recorded is included.
• Accuracy and cutoff address correct amounts and the correct accounting period.
• Classification asks whether transactions appear in the proper accounts.

Account balance assertions commonly include existence, rights and obligations, completeness, and valuation and allocation.

• Existence asks whether recorded assets, liabilities, and equity interests are real at the reporting date.
• Rights and obligations asks whether the entity owns the assets and owes the liabilities.
• Completeness asks whether all balances that should be recorded are included.
• Valuation and allocation asks whether balances and related adjustments are measured properly.

Presentation and disclosure assertions address occurrence and rights, completeness, classification and understandability, and accuracy and valuation.

• Occurrence and rights asks whether disclosed events happened and concern the entity.
• Completeness asks whether all required disclosures are present.
• Classification and understandability asks whether information is organized and described clearly.
• Accuracy and valuation asks whether disclosed amounts and other information are stated appropriately.

Generally Accepted Auditing Standards are the standards that govern how auditors plan, perform, document, and report an audit in the relevant jurisdiction.

• They establish requirements for competence, independence, professional judgment, evidence, and reporting.
• In the United States, the applicable standard setter depends on the engagement, such as the AICPA for many private entities and the PCAOB for public companies.
• Standards set the required quality of work but do not replace judgment about the specific engagement.

International Standards on Auditing are audit requirements and application guidance issued by the IAASB for financial statement audits.

• ISAs cover topics such as risk assessment, evidence, documentation, completion, and reporting.
• A jurisdiction may adopt the ISAs directly or adapt them into local standards.
• IFRS governs financial reporting, while ISAs govern the audit of that reporting.

An audit provides reasonable assurance because it reduces audit risk to an acceptably low level but cannot eliminate it.

• Auditors use selective testing rather than examining every transaction and document.
• Accounting estimates involve uncertainty and reasonable judgments can differ.
• Fraud may involve collusion, forgery, or management override that conceals evidence.
• Audit evidence is often persuasive rather than conclusive.

The inherent limitations of an audit arise from the nature of financial reporting, audit procedures, and practical time and cost constraints.

• Financial statements include estimates and judgments that cannot be verified with complete certainty.
• Sampling means some items are not directly tested.
• Controls can fail through human error, collusion, or management override.
• Reporting deadlines require the auditor to form a conclusion within a reasonable period.

Professional skepticism is an alert, questioning mindset that critically assesses audit evidence.

• The auditor remains attentive to contradictions, unusual conditions, and evidence that may be unreliable.
• Skepticism means verifying significant claims rather than assuming management is either honest or dishonest.
• When evidence conflicts, the auditor investigates the difference instead of selecting the more convenient source.

Professional judgment is the reasoned application of training, knowledge, and experience to decisions required by auditing and accounting standards.

• It is used when setting materiality, assessing risks, selecting procedures, and evaluating estimates.
• A sound judgment considers relevant facts, alternatives, and the requirements of the applicable standards.
• The rationale must be documented clearly enough for an experienced auditor to understand it.

An auditor follows integrity, objectivity, professional competence and due care, confidentiality, and professional behavior.

• Integrity requires honest and straightforward work and communication.
• Objectivity requires avoiding bias, conflicts of interest, and undue influence.
• Competence and due care require maintaining knowledge and performing work diligently.
• Confidentiality limits improper use or disclosure of client information.

Independence in fact is an unbiased state of mind, while independence in appearance means avoiding circumstances that a reasonable observer would view as compromising objectivity.

• A financial interest in an audit client can impair both forms of independence.
• Even an auditor who feels objective must consider how close relationships or services look to outsiders.
• Independence requirements apply throughout the engagement and are checked before work begins.

Common independence threats include self-interest, self-review, advocacy, familiarity, and intimidation.

• A self-interest threat can arise from a financial interest or dependence on client fees.
• A self-review threat arises when the firm audits work it previously performed for the client.
• A familiarity threat can develop from a close or long-standing personal relationship.
• Safeguards may include removing a person from the team, an independent review, or declining the engagement when the threat cannot be reduced.

The audit risk model expresses audit risk as the relationship among inherent risk, control risk, and detection risk.

• Inherent risk and control risk together describe the risk of material misstatement before the auditor's work.
• Detection risk is the risk that audit procedures fail to find an existing material misstatement.
• When assessed risk of material misstatement is higher, the auditor accepts less detection risk and performs more persuasive work.

Inherent risk is the susceptibility of an assertion to material misstatement before considering related controls.

• Complex calculations, estimation uncertainty, and rapidly changing conditions can increase inherent risk.
• Cash is inherently vulnerable to theft because it is easily transferable.
• The auditor assesses inherent risk by considering both the likelihood and magnitude of a possible misstatement.

Control risk is the risk that the entity's internal controls will not prevent, or detect and correct, a material misstatement on time.

• A missing review, poor segregation of duties, or an ineffective system rule can raise control risk.
• The auditor learns how relevant controls are designed and implemented before deciding whether to rely on them.
• If controls are not reliable, the audit response normally places more emphasis on substantive procedures.
