Understanding the Big 4 Interview Process
The typical interview process consists of several stages:
First is the initial screening, usually conducted by HR or a recruiter. This focuses on your background, interest in the firm, and basic qualifications. Next comes the first-round interview with senior associates or managers, followed by final rounds with partners or directors. Some firms may include group interviews or assessment centers.
Behavioral Interview Preparation
The STAR Method
When answering behavioral questions, use the Situation, Task, Action, Result framework. For example, if asked about handling a difficult team situation, you might say:
Situation: “During my internship at a mid-sized accounting firm, our audit team faced a tight deadline with a challenging client.”
Task: “We needed to complete the inventory audit while dealing with incomplete documentation.”
Action: “I created a detailed checklist and worked with the client’s inventory manager to locate missing documents.”
Result: “We completed the audit on time, and the senior manager commended our team’s thoroughness.”
Key Behavioral Questions and Sample Answers
“Tell me about a time you had to maintain professional skepticism.”
Sample Answer: “While conducting accounts receivable testing during my internship, I noticed unusually large credit memos issued after year-end. Although the client explained these as routine adjustments, I discussed my concerns with my senior. We discovered the credit memos were masking collection issues, leading to important adjustments in the allowance for doubtful accounts.”
“How do you handle tight deadlines?”
Sample Answer: “During busy season at my previous firm, I managed multiple client engagements by creating detailed work plans with clear milestones. I communicated regularly with team members about progress and potential bottlenecks. When one client provided delayed documentation, I reprioritized tasks to maintain productivity while waiting for information.”
Technical Knowledge Assessment
Accounting Principles and Standards
Understand key accounting concepts thoroughly:
Revenue Recognition (ASC 606):
Be prepared to discuss the five-step model:
- Identify the contract
- Identify performance obligations
- Determine transaction price
- Allocate transaction price
- Recognize revenue when/as performance obligations are satisfied
Lease Accounting (ASC 842):
Understand the differences between operating and finance leases, and how they affect financial statements. Be ready to discuss implementation challenges and practical expedients.
Audit Concepts and Procedures
Risk Assessment:
Understand the relationship between inherent risk, control risk, and detection risk. Be prepared to discuss how these affect audit planning and procedures.
Substantive Testing:
Know various testing methods and when to apply them:
- Confirmation procedures
- Physical observation
- Documentation review

- Recalculation and reperformance
Industry-Specific Knowledge
Demonstrate understanding of specific industries relevant to the office you’re interviewing with. For example, if interviewing in New York, be familiar with financial services regulations and challenges.
Case Study Approach
Many Big 4 interviews include case studies. Here’s how to approach them:
Framework for Analysis
- Understand the Question
Read carefully and ask clarifying questions: “Am I correct in understanding that we’re focusing on revenue recognition for a software company with multiple service components?” - Identify Key Issues
Break down complex problems into manageable components: “The main considerations here are separate performance obligations, allocation of transaction price, and timing of revenue recognition.” - Apply Technical Knowledge
Show how accounting principles apply to the specific situation: “Under ASC 606, we need to determine whether the software license and maintenance services are distinct performance obligations.” - Consider Business Impact
Discuss broader implications: “This treatment will affect not only financial statements but also tax planning and compensation structures.”
