Questions to Ask During a Big 4 Interview (That Actually Impress)

How Deloitte, KPMG, EY, and PwC Judge the Questions You Ask

Most candidates spend weeks rehearsing answers to Big 4 interview questions — and then blank when the interviewer says "Do you have any questions for me?" Deloitte, KPMG, EY, and PwC interviewers pay close attention to that moment. The questions you ask reveal preparation, strategic thinking, and genuine curiosity — exactly what all four firms are actively screening for.

Here's what to ask, why each question lands, and how to tailor your approach depending on which firm is across the table.

Why Each Firm Is Listening for Something Different

All four firms look for similar talent — but they're shaped by distinct cultures, and your questions should reflect that.

1. Deloitte — Emphasises purpose-driven work and cross-industry collaboration. Questions that reference Deloitte's "Make an impact that matters" ethos, or their growing sustainability and ESG consulting practice, tend to resonate.
2. KPMG — Values structured development, integrity, and clear career pathways. Questions about mentorship programs, the associate-to-manager timeline, and KPMG's professional qualification support go down well here.
3. EY — Runs strengths-based interviews designed to surface authentic enthusiasm. Questions that connect your interests to EY's "Building a better working world" mission feel natural in this format — and non-rehearsed.
4. PwC — The global audit and advisory leader with strong international mobility. Questions about cross-service line exposure or PwC's global development programs signal real ambition, not just a desire to get the job.

Who Benefits — and How to Frame It

Strong questions serve different purposes depending on where you are in your career.

• For Students and Entry-Level Candidates: This is your chance to prove you've gone beyond the firm's careers page. Reference a recent initiative, a specific graduate scheme detail, or a new service line expansion. That level of preparation is noticed — and it opens the door to more interesting conversations.

• For Experienced Professionals: Lateral hires should ask about client portfolio composition, deal flow pace in the practice area, and how the firm handles knowledge transfer when onboarding people from outside.
• For Candidates Comparing Firms: Questions about day-to-day team structure, partner access, and internal culture differences give you genuine information to make your decision — and they signal maturity to the interviewer.

Six Questions That Actually Start Real Conversations

Most candidates ask the same two or three generic questions. These are the ones that land differently:

• "What does a successful first year look like in this role?" — Shows you're thinking beyond the offer and already planning to contribute. The framing shift is immediately noticeable.
• "How does the team approach knowledge-sharing across service lines?" — Signals cross-functional awareness, which matters at firms where audit, tax, and advisory teams often work the same clients.
• "What's one area you see the firm investing in that isn't mainstream yet?" — Strategic and forward-looking. Interviewers often give candid, revealing answers to this one.
• "How has your own career path evolved since joining?" — Personalises the conversation, builds genuine rapport, and gives you real data on internal mobility and progression speed at that specific firm.
• "What do you wish you'd known before your first client engagement?" — Disarming and practical. Tends to generate honest answers that give you a head start on what actually matters on the job.
• "How does the firm support professional qualifications — ACA, CPA, ACCA?" — Shows long-term commitment to the profession, not just the role. Signals you're thinking about your development, not just the job title.

How to Prepare Your Questions Before the Day

The best interview questions aren't improvised — they're prepared with the same discipline as your STAR examples.

1. Research recent firm news: Check each firm's press room for announcements on AI investments, sustainability reports, acquisitions, or new practice lines. A question that references something specific — "I saw Deloitte just expanded its green finance advisory team" — immediately signals you're engaged.
2. Know who you're meeting: Look up your interviewer on LinkedIn before the interview. A Senior Manager in tax advisory will have very different answers about day-to-day work than a Graduate Recruiter. Tailor your questions accordingly.
3. Prepare 4–5, plan to use 2–3: Some of your questions will get answered naturally during the conversation. Having extras means you're never caught empty-handed when they hand you the floor.
4. Avoid questions Google can answer: "What does KPMG do?" wastes the room. Ask what only a human insider can actually tell you.

Events Where You Can Ask These Questions in Advance

The best time to ask these questions isn't always the formal interview — it's the events that happen before applications even open.

• Diversity & Inclusion insight days — All four firms host these; small-group formats often include direct Q&A with partners and senior managers.
• Virtual open days — Give you access to recruiters in an informal setting where genuine questions are welcomed and remembered.
• Graduate recruitment webinars — Deloitte, KPMG, EY, and PwC run these ahead of peak season; ideal for asking about program structure and application timelines.
• Practice area insight sessions — Tax, audit, advisory, and technology teams each run targeted sessions where your service-line-specific questions will hit differently.
• On-campus firm presentations — The best place to build name recognition with recruiters before your application goes in.

Own the Conversation

The interview was never supposed to be one-directional. Deloitte, KPMG, EY, and PwC actively want to see curiosity — candidates who are thinking about the career they want to build, not just the offer they want to receive.

When you ask a strong question, you stop being another applicant in the queue. You become a person the interviewer remembers when the debrief starts.

Prepare your questions with the same purpose and specificity you bring to your STAR examples. They're not filler — they're your last impression.
