Getting a call from any of the Big 4 – Deloitte, PwC, EY, or KPMG – is every CA's dream. But once that email hits your inbox, excitement quickly turns into anxiety. “What will they ask?” “How do I stand out?” “What if I mess up?”
Well, take a deep breath. You’ve already done the hard part—clearing CA. Now, let’s prepare you for the final hurdle: the interview.
In this blog, we’ll walk you through real interview questions asked at Big 4 firms and provide sample answers (written like a real person would speak, not like a textbook). No jargon, no robotic responses. Just practical stuff you can actually use.
What Big 4 Firms Look For in a CA
Before jumping into questions, it’s important to understand what interviewers are testing for:
- Technical clarity (Accounting Standards, Audit, Tax)
- Commercial awareness (business thinking)
- Communication and confidence
- Willingness to learn and grow
- Ethical mindset
Now let’s break it down firm-wise, because each Big 4 has its own flavor.
Deloitte Interview Questions for CAs
1. Walk me through your articleship experience.
Answer: I worked at a mid-size firm, where I handled statutory audits for manufacturing clients. I also got exposure to GST compliance and individual tax returns. I took the initiative to automate some audit working papers using Excel macros, which reduced our review time. The variety of work really helped me learn to manage deadlines and juggle multiple client expectations.
2. How would you audit the fixed assets of a company?
Answer:I’d start by understanding the client’s capitalization policy, then obtain the FA register. I’d verify additions through invoices and approvals, and perform physical verification on a sample basis. I’d also recalculate depreciation and check for any impairment indicators.
3. Why Deloitte?
Answer: Because Deloitte doesn’t just audit books—it shapes businesses. I admire the focus on innovation, like how you’re investing in AI-led audits. I want to be part of a firm that challenges traditional thinking and allows me to grow beyond just numbers.
4. Tell us about a challenging audit client and how you handled it.
Answer: "One client delayed sharing key data. I scheduled weekly check-ins, built rapport with their team, and created a shared Google sheet to track pending items. It helped us complete the audit within the deadline.
5. How do you ensure audit quality under tight deadlines?
Answer: I prioritize risk areas and focus early on key assertions. I also delegate lower-risk testing and always maintain documentation simultaneously to save end-time pressure.
6. How would you handle a situation where you find fraud indicators?
Answer: I'd document my observations, gather preliminary evidence, and escalate to my senior/manager. I believe in acting responsibly but within the firm's reporting lines.
7. What recent financial news caught your attention?
Answer: The recent CBDT clarification on Section 43B(h) was interesting. It affects MSME payments and could significantly impact balance sheet liabilities across companies.
EY Interview Questions for CAs
1. Tell me about a time you faced an ethical dilemma.
Answer: During my articleship, a client asked me to backdate an invoice to avoid late fees. I politely refused and escalated the matter to my manager. We resolved it by explaining the risks involved. I believe in transparency and long-term trust over short-term gains.
2. How do you stay updated with changes in tax laws?
Answer: I follow Taxsutra and CAclubindia, and I read the Economic Times daily. I also make short notes from ICAI notifications. It’s a habit I formed during CA prep—it helps me stay sharp.
3. How would you explain GST to someone from a non-finance background?
Answer: I’d say GST is like a national-level tax that replaced many small taxes. It makes business easier because now you pay tax on value addition, not on the entire transaction. It’s like paying tax only on the profit portion at each stage.
4. What do you know about EY's service lines?
Answer: EY has Assurance, Consulting, Strategy and Transactions, and Tax. I’m particularly drawn to Assurance because of the evolving role of technology in audits.
5. Explain a complex accounting standard in simple terms.
Answer: Ind AS 116 on leases: It says most leases must now be shown on the balance sheet, both as an asset and a liability. It’s like saying, 'If you're renting a house, show that house and the rent due in your books.
6. Describe a client situation where you had to be diplomatic.
Answer: During a statutory audit, the CFO was quite defensive about a revenue recognition observation we raised. I understood it was a sensitive point for their year-end reporting. I acknowledged his perspective and calmly explained the applicable Ind AS guidance and our audit procedures. I offered to walk him through the documentation and even involved my manager to ensure alignment. In the end, he appreciated our transparency and the issue was resolved professionally.
8. Why EY?
Answer: EY stands out because it combines technical excellence with a strong people-first culture. I admire the way EY invests in talent through programs like EYU and offers real global mobility options. I want to work in an environment that values continuous learning, diversity, and encourages young professionals to take ownership of their growth. EY’s strong client portfolio and digital-first approach also align with the kind of exposure I’m seeking early in my career.
PwC Interview Questions for CAs
1. What are your views on audit independence?
Answer: Auditor independence is everything. Even the perception of bias can damage trust. That’s why I believe in keeping professional distance, saying no to conflicts, and being transparent in communication.
2. If a client offers you a gift during the audit, what would you do?
Answer: I’d politely decline and explain that I follow ICAI’s Code of Ethics. Even a small gift can cloud judgement or raise questions later. I prefer to maintain a clean image.
3. Have you ever missed a deadline? How did you handle it?
Answer: Yes, once during my articleship, a tax return filing was delayed because of late data from the client. I informed my senior proactively, followed up with the client, and prioritized the filing once data was received. It taught me the value of communication and contingency planning.
4. Why PwC?
Answer: PwC’s focus on digital transformation and ESG aligns with my interest in future-ready audits. I also value the culture of mentorship, global learning programs, and opportunities to work across diverse industries and geographies.
5. Describe your experience with audit tools or software.
Answer: I’ve worked with CaseWare and Tally for audit documentation and accounting. I also used Excel macros to automate sampling and reconciliations. I enjoy exploring tools that enhance efficiency, and I’m eager to learn PwC's Aura system and how it integrates analytics into audit execution.
6. What are the challenges of auditing startups?
Answer: Auditing startups can be tricky due to limited internal controls, informal processes, and mixed personal-business transactions. Many lack proper documentation or SOPs. It requires auditors to apply judgment carefully while maintaining audit quality and offering constructive feedback without disrupting the client relationship.
7. How do you handle client pressure during peak season?
Answer: I approach pressure by setting daily priorities, communicating clearly with clients, and managing expectations early. I stay focused on high-risk areas, ensure team coordination, and break down complex tasks into manageable steps to maintain quality under tight timelines.
8. What are key differences between Stat Audit and Internal Audit?
Answer: Statutory Audit ensures the financials present a true and fair view, mainly for shareholders and regulators. Internal Audit focuses on reviewing internal processes, identifying inefficiencies, and improving controls to help management make informed decisions and reduce operational risks.
KPMG Interview Questions for CAs
1. Tell me about a financial reporting standard you find challenging.
Answer: Ind AS 115 on Revenue Recognition was tricky at first—especially with contract modifications. But I found breaking down the five-step model into use-case examples really helped. I believe in simplifying things for better understanding.
2. Tell me about your favorite area in auditing.
Answer: I enjoy audit planning and risk assessment because it allows me to think strategically. Identifying key risk areas early sets the foundation for the entire engagement. I like analyzing a business, understanding its operations, and designing a tailored audit approach. It feels like solving a puzzle from the very beginning.
3. Explain going concern assumption with an example.
Answer: Going concern assumes a company will continue operating in the near future. For example, if a business is running at a loss but has secured new funding or a line of credit, the going concern assumption still holds because it has the resources to continue operations.
4. Why KPMG?
Answer: KPMG stands out for its technical excellence and strong training programs. The exposure to global clients, combined with structured learning paths, makes it an ideal environment for a young CA like me who wants to build a deep and wide-ranging skillset from the start.
5. What do you do when a client is being non-cooperative?
Answer: I remain calm and respectful, explain why we need certain information, and try to reschedule or find a more convenient approach. If cooperation is still an issue, I document everything and escalate to the engagement manager to ensure resolution without damaging the client relationship.
6. How do you handle tasks you’re unfamiliar with?
Answer: When I encounter something new, I break it down, research the fundamentals, and try it hands-on. If I hit a roadblock, I seek help from colleagues. I view unfamiliar tasks as opportunities to grow, and my curiosity helps me grasp concepts quickly.
7. What are key risks in revenue audit?
Answer: Revenue is prone to misstatements like fictitious sales, early recognition, and cut-off errors. I focus on verifying sales invoices, delivery records, and matching revenue with actual performance obligations. Proper understanding of Ind AS 115 and walkthroughs of revenue cycles help mitigate these risks effectively.
