Big 4 Internship Comparison: PwC vs Deloitte vs EY vs KPMG
A side-by-side look at the four largest professional services firms — their internship programmes, recruitment timelines, culture, pay, and the realistic odds of converting an internship into a graduate offer.
Why the Big 4 internships matter
PwC, Deloitte, EY and KPMG together hire more than 40,000 interns a year worldwide. For most of them, the summer internship is the single biggest gateway into a graduate role — conversion rates sit between 65% and 90% depending on firm, service line, and country.
The four firms look similar from the outside, but the day-to-day experience, the work you get exposed to, and the path to a return offer differ in meaningful ways. This guide breaks down what actually changes between them.
The Big 4 at a glance
PwC (PricewaterhouseCoopers)
Trust-led, audit-strong, with the broadest global footprint.
Deloitte
Consulting-heavy, fastest-growing, strong tech & strategy practice.
EY (Ernst & Young)
Strong tax & transaction advisory, deep focus on long-term careers.
KPMG
Audit-first, leanest of the Big 4, most personal intern experience.
Recruitment timeline — when to apply
All four firms use a rolling assessment: applications close when cohorts fill, not on the published deadline. In practice that means popular offices (London, New York, Sydney, Singapore, Dubai, Johannesburg) close 4–8 weeks early.
- August–September: PwC and Deloitte open first. Submit applications here for the best office choice.
- October–November: EY and KPMG open. Online assessments and video interviews run in parallel.
- December–February: Assessment centres and partner interviews.
- March–May: Offers and pre-onboarding.
- June–August: Internships run, with return-offer decisions issued within 2–4 weeks of the end date.
Cultural differences that actually show up
PwC (PricewaterhouseCoopers)
Coaching-heavy, structured, formal. Big emphasis on Purpose and ESG.
Deloitte
Entrepreneurial, fast, project-driven. Higher travel expectations in Consulting.
EY (Ernst & Young)
Collaborative, values-driven ("Building a better working world"), strong DEI investment.
KPMG
Smaller teams, more partner exposure, traditional professional services feel.
Pay and benefits
Big 4 intern pay is closely benchmarked across firms in each market. In London, expect roughly £500–£600 per week for a summer internship; in New York, $35–$45 per hour; in Sydney, AUD 1,200–1,400 per week. Consulting interns typically sit at the top of the range.
- PwC: Strong base, formal training stipend, sponsored professional qualifications post-conversion.
- Deloitte: Top of market for Consulting; travel-related allowances; widest perks catalogue.
- EY: Competitive base plus wellbeing and learning credits (Udemy, Coursera).
- KPMG: Marginally lower base in Consulting, offset by stronger mentoring time per intern.
Which Big 4 internship should you pick?
PwC (PricewaterhouseCoopers)
Students who want assurance / tax depth, formal coaching and a recognisable brand on the CV.
Deloitte
Students targeting Consulting, Strategy, or Technology — and who like a faster-paced environment.
EY (Ernst & Young)
Students drawn to Tax, M&A, or sustainability advisory who want a longer placement option.
KPMG
Students who want closer mentorship, smaller cohorts, and a clear path into Audit or Risk.
How to maximise your odds
- Apply to two Big 4 firms, not all four — quality of application beats quantity.
- Tailor your motivation answer to the firm's stated values (Purpose at PwC, Better Working World at EY).
- Practice numerical and situational judgement tests for at least 10 hours before your live attempt.
- Prepare two STAR stories per competency (teamwork, leadership, resilience, commercial awareness).
- At the assessment centre, ask one well-researched question per partner — it is the single biggest differentiator.
FAQ
Which Big 4 internship pays the most?
Pay is tightly clustered across the Big 4. In most markets Deloitte and PwC lead for Consulting interns, while Audit pay is essentially identical across all four. EY and KPMG often close the gap with stipends, transport, or wellbeing benefits.
Which Big 4 has the highest intern-to-graduate conversion rate?
Deloitte typically reports the highest conversion (often 80%+ in Consulting), followed by PwC and EY in the 70s. KPMG sits in a similar range with smaller cohorts and more personalised feedback.
Do you need an accounting degree to intern at a Big 4 firm?
No. Audit and Tax favour accounting and finance backgrounds, but Consulting, Risk, Technology and Strategy hire from any discipline — engineering, economics, computer science, law, and the humanities are all common.
When should I apply for Big 4 internships?
Open applications run from August to November for the following summer in most markets. Apply early — Big 4 firms use rolling assessment, so spots in popular offices close before the official deadline.
Is a Big 4 internship worth it?
Yes for most students: structured training, recognised brand, and a near-direct pipeline to a graduate offer. The trade-off is long hours during busy season and a formal corporate culture compared to startups.
