Deloitte vs EY consulting comes down to a few key trade-offs: size, prestige tier, pay, interview style, and the strength of each firm's strategy brand. Deloitte is the larger, more prestigious, and slightly better-paying firm. EY offers a more collegial culture, better work-life balance, and the largest strategy practice of any Big Four consulting firm through EY-Parthenon.

 

By the end of this article, you will know exactly how Deloitte and EY differ across the dimensions that matter for your career, and which firm is the better fit for your goals.

 

But first, a quick heads up:

 

McKinsey, BCG, Bain, and other top firms accept less than 1% of applicants every year. If you want to triple your chances of landing interviews and 8x your chances of passing them, watch my free 40-minute training.

 

What Is the Difference Between Deloitte and EY Consulting?

 

Deloitte is the larger and generally more prestigious of the two firms. Its consulting practice is broader, more recognized, and pays slightly more at most levels. EY has invested heavily in strategy through EY-Parthenon and is now the largest strategy and transactions house in the Big 4, but its broader consulting brand still trails Deloitte in overall prestige.

 

Here is a quick side-by-side comparison of the two firms:

 

Dimension	Deloitte	EY
Global revenue (FY2025)	$70.5 billion	$53.2 billion
Global employees	~460,000	~406,000
Countries	150+	150+
Consulting prestige	Top of Big 4	Mid Big 4
Strategy brand	Monitor Deloitte (~6,000 staff)	EY-Parthenon (~25,000 staff)
Culture	Competitive, growth-driven	Collegial, balanced
Work-life balance	55 to 65 hours typical	50 to 60 hours typical
Compensation (consultant level)	$100K to $115K base	$95K to $110K base
Acceptance rate (consulting)	~3% to 5%	~5% to 8%

 

If you want maximum optionality across strategy, technology, and operations work under one of the most recognized brands in consulting, Deloitte usually wins. If you want a leaner culture, a strong path into private equity strategy work, or a faster track to client-facing transformation projects, EY is a strong choice.

 

How Do Deloitte and EY Compare on Size and Revenue?

 

Deloitte is significantly larger than EY in both revenue and headcount. In fiscal year 2025, Deloitte reported $70.5 billion in global revenue versus EY's $53.2 billion, according to each firm's annual revenue announcement. Deloitte also leads in employees, with roughly 460,000 worldwide compared to EY's 406,206.

 

Here is how the two firms compare by the numbers in 2025:

 

Metric	Deloitte	EY
Global revenue (FY2025)	$70.5 billion	$53.2 billion
Revenue growth (FY2025)	4.8%	4.0%
Global employees	~460,000	406,206
Countries served	150+	150+
Year founded	1845	1989 (merger)
Headquarters	London	London
Fiscal year ends	May 31	June 30

 

Deloitte's consulting practice alone is the largest in the world, generating an estimated $30 billion in annual revenue. EY's consulting business is smaller, but it grew 5.2% in fiscal year 2025 and saw a 30% rise in AI-related services. Both firms operate in more than 150 countries.

 

In raw scale, Deloitte wins. Deloitte's consulting practice is roughly twice the size of EY's, which translates to more client relationships, more open roles, and a deeper bench of subject matter experts. EY counters with focused investments in strategy and transactions through EY-Parthenon, which expanded to a 25,000-person organization in 2025.

 

Which Firm Is More Prestigious: Deloitte or EY?

 

Deloitte is generally seen as more prestigious than EY in the consulting market. Insider rankings and candidate forums consistently place Deloitte's consulting practice at the top of the Big 4, with EY ranking second or third alongside PwC. The prestige gap is small for most candidates and matters less than the specific practice area you join.

 

The prestige picture flips inside strategy specifically. EY-Parthenon is widely viewed as the most credible strategy brand in the Big 4 because it operates as a more separate strategy house with heavy private equity work. Monitor Deloitte, by contrast, has been absorbed into Deloitte's broader Strategy and Analytics practice in most U.S. regions, which diluted its standalone strategy brand.

 

Outside of strategy, prestige typically breaks down by practice area:

 

• Top of Big 4 at Deloitte: technology, human capital, operations, government and public services

 

• Top of Big 4 at EY: strategy through EY-Parthenon, financial services advisory, transactions, sustainability and ESG

 

• Roughly tied: risk advisory, M&A diligence, tax advisory, cyber

 

For candidates aiming at MBB consulting eventually, both firms are viable launchpads, but Deloitte names tend to carry slightly more weight on a resume outside of strategy roles. Inside strategy, EY-Parthenon is the stronger jumping-off point.

 

How Do Deloitte and EY Consulting Salaries Compare?

 

Deloitte pays consultants slightly more than EY at most levels, but the gap is smaller than people assume. According to Glassdoor and Levels.fyi data from 2026, base salary differences usually fall in the $5,000 to $15,000 range at junior and mid-level positions. The gap can widen at the Director and Partner levels, where Deloitte's larger consulting practice typically pays out larger bonuses.

 

Here is a 2026 U.S. total compensation comparison by level:

 

Level	Deloitte (total comp)	EY (total comp)
Analyst (undergrad)	$90K to $115K	$85K to $110K
Consultant	$110K to $150K	$105K to $145K
Senior Consultant	$150K to $200K	$140K to $190K
Manager	$200K to $260K	$190K to $245K
Senior Manager	$260K to $340K	$245K to $320K
Managing Director or Partner	$500K to $1M+	$450K to $900K+

 

Strategy units pay above the standard Big 4 scale at both firms. At the MBA level, EY Strategy and Operations total compensation hits around $268,000, according to 2026 industry compensation reports. Monitor Deloitte pays in a similar band but is no longer fully separate from the broader Deloitte Consulting compensation structure in the U.S.

 

Bonuses are typically larger at Deloitte than at EY. Year-end performance bonuses at Deloitte can run 15% to 25% of base salary at the consultant level, while EY bonuses more often fall in the 10% to 18% range, based on Glassdoor data from 2026.

 

One important note: practice area and region matter more than firm name for total compensation. A senior consultant in Deloitte's New York technology practice will earn more than an EY counterpart in a smaller market, but the gap may flip in a market like Atlanta or Boston. Do not pick one firm over the other for a $5,000 base salary difference.

 

What Are the Practice Areas and Strategy Brands at Deloitte and EY?

 

Deloitte and EY both organize consulting into multiple service lines, but the structure and naming differ. Deloitte has historically kept consulting under one large umbrella, while EY runs strategy as a more separate unit under EY-Parthenon.

 

Deloitte's main consulting service lines include:

 

• Strategy and Analytics (which absorbed Monitor Deloitte in the U.S.)

 

• Customer and Marketing

 

• Core Business Operations

 

• Human Capital

 

• Enterprise Performance

 

• Mergers, Acquisitions, and Restructuring

 

• Technology Consulting

 

EY's main consulting and advisory service lines include:

 

• EY-Parthenon (Strategy, Transactions, and Restructuring)

 

• Technology Consulting

 

• Business Consulting (Performance Improvement, Risk)

 

• People Advisory Services

 

• Climate Change and Sustainability Services

 

• Forensic and Integrity Services

 

EY-Parthenon expanded in 2025 to become a 25,000-person strategy and transactions house operating across 150 countries, the largest strategy practice of any Big 4 firm by headcount, according to Consultancy.eu reporting on EY's announcement. Monitor Deloitte, by comparison, has roughly 6,000 strategy professionals globally. PwC's Strategy& has around 4,500 and KPMG's Global Strategy Group has around 4,000.

 

The structural difference matters for your day-to-day work. At EY-Parthenon, you will sit inside a more separate strategy unit with its own recruiting, training, and project portfolio (heavy on private equity commercial due diligence). At Deloitte, strategy work is more integrated with the broader consulting practice, which means you may rotate across pure strategy, operations, and digital transformation projects within a single year.

 

How Do the Interview Processes Differ at Deloitte and EY?

 

The interview processes at Deloitte and EY are similar in structure but differ in case format and final round design. Both firms run a 2-round interview process after an initial resume screen and online assessment. Deloitte tends to use shorter, more structured cases with a group case in the final round. EY uses longer, candidate-led cases with both a group case and a one-on-one written or oral case in the final round.

 

Here is a side-by-side comparison of the two interview processes:

 

Stage	Deloitte	EY
Online assessment	Immersive scenario assessment	Numerical, verbal, and situational tests
First round	1 behavioral + 1 to 2 case interviews (30 to 45 min each)	2 interviews with consultants or managers (case + fit, 30 to 45 min each)
Final round	1 behavioral + 1 case + 1 group case (1 hour)	1 behavioral + 1 case + 1 group case (60 to 75 min)
Case format	Candidate-led, often with written materials	Candidate-led, PE-heavy for EY-Parthenon
Group case used?	Yes (final round)	Yes (final round)
Total length	2 to 8 weeks	3 to 10 weeks

 

How Does the Deloitte Interview Process Work?

 

The Deloitte interview process has three main stages: an online application and assessment, a first round of interviews, and a final round. First round interviews are typically two 45-minute interviews, each combining behavioral and case questions, conducted with consultants or junior managers.

 

Each Deloitte case interview is candidate-led and runs 30 to 45 minutes. Final round interviews include longer case discussions, a behavioral interview with senior leaders, and a group case interview where 3 to 5 candidates collaborate on a business problem. Roughly 80% of Deloitte final round candidates encounter a group case, based on Glassdoor data.

 

How Does the EY Interview Process Work?

 

EY's interview process runs three to four stages, depending on practice. After the application and online assessment, candidates complete a video screening interview, then a first round with consultants and managers, and finally a structured final round with senior leaders.

 

The final round typically includes a behavioral interview, a one-on-one case interview, and a group case interview lasting 60 to 75 minutes. The group case is a defining feature of EY's process and tests how well you collaborate with peers under time pressure, according to candidate reports on Glassdoor.

 

If you are applying to EY-Parthenon, the cases are heavier on private equity, market entry, and commercial due diligence topics. The structured EY-Parthenon case interview format mirrors what you would see at MBB firms more closely than EY's broader consulting interviews. Expect three to four cases across two rounds.

 

What Are the Cultural Differences Between Deloitte and EY?

 

Deloitte and EY have different work cultures, even though both are large Big 4 firms. Deloitte is generally described as more competitive, more aggressive on growth, and more performance-driven. EY is generally described as more collegial, more focused on work-life balance, and more relaxed in day-to-day team dynamics.

 

Here is a side-by-side cultural comparison based on Glassdoor reviews and candidate forum data from 2025 and 2026:

 

Cultural Aspect	Deloitte	EY
Glassdoor rating	3.9 / 5 (126,000+ reviews)	3.9 / 5 (10,000+ reviews)
Work pace	Fast, growth-driven	Steady, balanced
Promotion competitiveness	High, partner-driven	Moderate, more collaborative
Typical hours per week	55 to 65	50 to 60
Team dynamics	Performance-focused	Relationship-focused
Best Places to Work recognition	Glassdoor BPTW (2018, 2019, 2023, 2024)	Multiple Fortune and DiversityInc awards

 

Deloitte's culture rewards people who push for promotion and visibility. Partners are often described as competitive with each other, and that competitiveness flows down into project staffing decisions. Several Fishbowl and Blind reviews from 2025 describe Deloitte as the best-run and best-paying Big 4 but also one where you need to perform consistently to thrive.

 

EY's culture, by contrast, is often described as more team-oriented, with managers more willing to protect junior staff from extreme hours. A common Blind comment from candidates choosing between the two is that EY has more relaxed culture and slightly better work-life balance, while Deloitte has stronger bonuses and more aggressive growth opportunities.

 

Neither culture is universally better. The right fit depends on whether you thrive in a high-pressure, growth-oriented environment or prefer a steadier, more relationship-driven one.

 

Which Firm Has Better Exit Opportunities?

 

Deloitte generally offers slightly better exit opportunities than EY because of its broader brand recognition and larger alumni network. Both firms send consultants into industry roles, private equity portfolio companies, and corporate strategy positions, but Deloitte's alumni networks are larger and more active in most major markets.

 

The most common exit paths from both firms include:

 

• Corporate strategy and operations roles at Fortune 500 companies

 

• Private equity portfolio operating teams (especially from EY-Parthenon)

 

• Industry roles in technology, healthcare, and financial services

 

• Top MBA programs followed by post-MBA consulting roles at MBB or returning at a higher level

 

• Internal moves to client companies where the consultant led a transformation

 

EY-Parthenon stands out for private equity exits. Because EY-Parthenon does a lot of commercial due diligence and value creation work for private equity clients, consultants there build direct relationships with PE firms. Monitor Deloitte exits look more similar to standard Deloitte Consulting exits in the U.S. market, with a heavier weighting toward Fortune 500 corporate strategy roles.

 

For lateral moves to MBB, both firms have meaningful placement track records. EY-Parthenon has over 160 Partners with prior McKinsey, BCG, or Bain experience globally, based on publicly available LinkedIn data. That signals the talent quality at EY-Parthenon is comparable to MBB, which makes the move credible.

 

Should You Choose Deloitte or EY Consulting?

 

Choose Deloitte if you want maximum brand recognition, the largest consulting practice in the world, slightly higher pay, and the broadest range of service lines and industries to rotate through. Choose EY if you want a more collegial culture, better work-life balance, or a path into strategy or private equity work through EY-Parthenon.

 

Here is a quick decision framework based on your goals:

 

• Best for prestige and broad consulting brand: Deloitte

 

• Best for strategy work and PE exits: EY (through EY-Parthenon)

 

• Best for work-life balance: EY

 

• Best for technology consulting: Deloitte

 

• Best for sustainability and ESG advisory: EY

 

• Best for highest total compensation at standard Big 4 scale: Deloitte

 

• Best for government and public sector consulting: Deloitte

 

• Best for financial services advisory: EY

 

• Best for the largest alumni network: Deloitte

 

If you have offers from both firms in the same practice area, the deciding factor is usually team fit and the partner you would be working under. Talk to your potential team, ask about the projects you would staff onto in your first six months, and choose the place where you connected most with the people. Both firms are excellent launchpads for a consulting career.

 

How Do You Prepare for Deloitte and EY Consulting Interviews?

 

The most effective prep combines case interview practice, behavioral story development, and firm-specific research. Both Deloitte and EY use the case interview format, so the core skill set you need is identical. The differences show up in how cases are delivered and what behavioral traits each firm emphasizes.

 

Here are the five steps you should take to prepare for either firm:

 

1. Build a solid foundation in case interview frameworks, case math, and structured thinking before any live practice.
   
   
2. Practice 25 to 50 live cases with a partner, including both individual cases and at least 3 to 5 group cases.
   
   
3. Prepare 5 to 7 behavioral stories that map to common consulting fit traits like leadership, teamwork, conflict resolution, and impact.
   
   
4. Research recent work at each firm and people you have spoken to during networking, so you can give a specific Why Deloitte or Why EY answer.
   
   
5. Do at least 3 mock interviews under realistic conditions in the final week before your interview.

 

Case interviews are critical at both Deloitte and EY. If you want to learn case interviews quickly, my case interview course walks you through proven strategies in as little as 7 days.

 

Frequently Asked Questions

 

Is Deloitte better than EY for consulting?

 

Deloitte is generally considered slightly better than EY for consulting because of its larger practice, broader brand recognition, and higher compensation at most levels. EY is competitive in strategy through EY-Parthenon and often offers better work-life balance. For pure strategy work and private equity exits, EY-Parthenon outperforms standard Deloitte Consulting in most markets.

 

Does Deloitte pay more than EY?

 

Yes, the Deloitte consulting salary tends to be slightly higher than EY's at most levels. According to Glassdoor data from 2026, the gap is usually $5,000 to $15,000 at the base salary level, with larger bonus differentials at senior levels. The gap is small enough that practice area and region typically matter more than firm name for total compensation.

 

Is it harder to get into Deloitte or EY?

 

Deloitte is generally harder to get into than EY at the consulting practice level. Deloitte Consulting has an estimated acceptance rate of 3% to 5%, while EY's broader consulting practice runs closer to 5% to 8%. EY-Parthenon, however, is more selective than standard Deloitte Consulting and operates closer to MBB acceptance rates.

 

Is EY-Parthenon better than Monitor Deloitte?

 

EY-Parthenon is generally considered a stronger standalone strategy brand than Monitor Deloitte today. EY-Parthenon operates as a more separate unit with heavy private equity work and grew to 25,000 people in 2025. Monitor Deloitte has been integrated into Deloitte's broader Strategy and Analytics practice in most U.S. regions, which reduced its independent brand value.

 

What is the work-life balance like at Deloitte vs EY?

 

EY generally offers better work-life balance than Deloitte. Hours at both firms vary by project and team, but EY consultants more frequently report 50 to 60-hour weeks compared to Deloitte's 55 to 65-hour averages, especially on strategy or transformation engagements. Several Blind and Fishbowl reviews from 2025 and 2026 describe EY as having a more relaxed culture than Deloitte.

 

Do Deloitte or EY consultants exit to MBB more often?

 

Both Deloitte and EY consultants successfully exit to MBB firms, with conversion rates highest for those in strategy practices. EY-Parthenon and Monitor Deloitte alumni both show meaningful placement rates at McKinsey, BCG, and Bain. Outside of strategy, Deloitte's larger alumni network gives it a slight edge in lateral moves to MBB.

 

Should I join Deloitte or EY if I want to go into private equity?

 

EY-Parthenon is the better choice if private equity is your goal. EY-Parthenon does extensive commercial due diligence and value creation work for private equity clients, which builds direct relationships with PE firms. Deloitte's M&A and Restructuring practice also opens PE doors, but the path is less direct than through EY-Parthenon.
