Internal auditing is an independent and objective assurance and consulting activity designed to evaluate and improve an organization’s risk management, internal control, and governance processes. Internal auditors examine business operations and recommend improvements.
2. What does an internal auditor do?
Answer:
An internal auditor reviews organizational processes, evaluates internal controls, identifies risks, tests compliance, examines financial and operational records, and communicates audit findings to management.

The main objective is to provide independent assurance that an organization’s risk management, governance, and internal control processes are functioning effectively.

Important skills include analytical thinking, attention to detail, communication, accounting knowledge, risk assessment, data analysis, professional skepticism, problem-solving, and report writing.

Answer:
Professional skepticism is a questioning mindset. It involves critically evaluating audit evidence instead of automatically accepting information or explanations without appropriate verification.
9. What is audit evidence?
Answer:
Audit evidence is information collected by an auditor to support audit findings and conclusions. Examples include invoices, contracts, reports, system records, observations, confirmations, and analytical results.
10. What is reasonable assurance?

Reasonable assurance is a high but not absolute level of confidence that significant risks, control weaknesses, or material issues have been appropriately identified and evaluated.
Internal Control Interview Questions
11. What is internal control?
Answer:
Internal control refers to policies, procedures, activities, and systems designed to help an organization achieve objectives, protect assets, maintain reliable information, and comply with requirements.
12. Why are internal controls important?
Answer:
Internal controls reduce risks, prevent or detect errors and fraud, safeguard assets, improve operational efficiency, and support accurate financial reporting.
13. What are preventive controls?
Answer:
Preventive controls are designed to stop errors or unauthorized activities before they occur. Examples include approval requirements, passwords, segregation of duties, and system access restrictions.
14. What are detective controls?
Answer:

Answer:
Segregation of duties means dividing important responsibilities among different individuals so that one person does not control an entire transaction from beginning to completion.

Answer:
It reduces the risk of errors, unauthorized activities, and fraud because multiple individuals participate in transaction processing, authorization, custody, and review.
18. Give an example of weak internal control.
Answer:
Allowing the same employee to create vendors, approve invoices, and process vendor payments is a weak control because the employee has excessive control over the purchasing and payment process.

A control deficiency exists when a control is missing, poorly designed, or not operating effectively enough to prevent or detect relevant risks.

Answer:
A risk-based audit focuses audit resources on areas with the greatest potential impact on organizational objectives.

38. What is audit sampling?
Answer:
Audit sampling involves examining a portion of a population to obtain evidence and draw conclusions about the larger population.
