assurance auditor Interview Questions and Answers

1. What is an assurance engagement?

   • Answer: An assurance engagement is a systematic process where an auditor provides a level of assurance on a subject matter to an intended user. This involves obtaining and evaluating evidence to determine the subject matter's reliability and conformity with established criteria.

2. Explain the difference between assurance and non-assurance services.

   • Answer: Assurance services provide a conclusion on a subject matter's reliability, whereas non-assurance services involve providing advice or other services without expressing an opinion or conclusion. Assurance engagements follow a structured methodology and provide a level of assurance, while non-assurance services are more flexible and lack a formal opinion.

3. What are the three levels of assurance?

   • Answer: The three levels of assurance are high (reasonable assurance), moderate, and limited (no assurance).

4. What is the difference between reasonable assurance and limited assurance?

   • Answer: Reasonable assurance provides a high level of assurance, implying that the auditor has performed extensive procedures to reduce the risk of material misstatement to a low level. Limited assurance involves less extensive procedures and provides a lower level of assurance, indicating that the auditor has performed enough procedures to provide a moderate level of comfort.

5. Describe the role of an assurance auditor.

   • Answer: An assurance auditor's role is to independently examine and evaluate the subject matter, obtain sufficient appropriate evidence, and provide an opinion or conclusion on the subject matter's reliability and conformity to criteria. This helps users make informed decisions based on credible information.

6. What are the key principles of auditing?

   • Answer: Key principles include independence, professional skepticism, due professional care, professional competence and due diligence, confidentiality, and integrity.
