Firm Overview: EY-Parthenon
If you are targeting EY-Parthenon, you are aiming for the strategy and transactions arm of EY that advises CEOs, boards and investors on high-stakes decisions like M&A, value creation and large scale transformations.
EY-Parthenon is the “transformative strategy and transactions” brand within EY. It grew out of the merger between the boutique Parthenon Group and EY’s Strategy & Transactions practice, and after a recent expansion it now counts more than 25,000 professionals in 120+ countries.
Work at EY-Parthenon spans:
- Corporate and business unit strategy
- Mergers, acquisitions and divestitures
- Commercial due diligence and value creation for private equity
- Turnaround and performance improvement
- Sector specific transformation and growth strategy
Focus and specialties
- Market entry or growth strategy for a consumer or tech company
- Commercial due diligence on a private equity buyout
- Portfolio and capital allocation strategy for a diversified corporate
- Turnaround planning for an underperforming unit or asset
Geography and scale
Offices are tightly integrated into EY’s global network, with major hubs in cities like New York, Boston, London, Paris, Dubai, Singapore and Sydney, plus many regional offices. Consultants often work cross border, especially on private equity and multinational corporate projects, though day-to-day travel patterns vary by region.
Why candidates choose EY-Parthenon
- High impact strategy work with blue chip clients and leading private equity funds
- The chance to work in sector focused teams and build deep expertise
- A culture that many describe as collaborative and pragmatic, with a bit less “up or out” intensity than some MBB offices, though this varies by location
Interview Process Overview
Undergraduate and entry level recruiting at EY-Parthenon typically uses two to three rounds. Experienced hire processes can involve extra steps, and some campus or regional “Super Days” combine rounds into a single day with morning and afternoon sessions.
Step 1: Screening:
Online application plus EY online assessments, often numerical / logical reasoning and sometimes a short recorded video interview focused on motivation and basic behavioral questions.
Step 2: First round:
One to two 45–60 minute interviews that mix fit questions with a structured case interview. Interviewers are usually consultants or managers who focus on problem solving approach, communication and basic business judgment.
Step 3: Final round:
Two to four interviews with more senior staff, including managers and partners. Many candidates encounter a group case or written / slide based case alongside one or two live cases. Final decisions hinge on client readiness, structured thinking, and cultural fit with the EY-Parthenon team.
Behavioral Interview
Across official materials and candidate reports, EY-Parthenon emphasises:
- Structured thinking and analytical rigor
- Curiosity and an “investor mindset”, especially in private equity and transactions work
- Teamwork and collaboration, particularly for group cases and large transformation engagements
- Inclusive leadership and low ego
- Client centric communication, including the ability to explain complex ideas simply
- Integrity and professional judgement, consistent with EY’s broader culture
The behavioral interview is where they test whether you will be someone partners are comfortable putting in front of clients and deal teams.
How to answer for EY-Parthenon
Using STAR or CAR for EY-Parthenon. Simple answer frameworks work best. STAR (Situation, Task, Action, Result) and CAR (Context, Action, Result) are both fine. For EY-Parthenon, CAR usually keeps your answers tighter and more outcome focused.
Example outline 1: Working with difficult stakeholders
Prompt: “Tell me about a time you had to influence a senior stakeholder who disagreed with you.”
- Context – 2 to 3 sentences. Where were you, what was the goal, who was the stakeholder and what did they want instead
- Action – 60 to 70 percent of your answer. How you prepared, what data or analysis you used, how you listened to their concerns, how you adjusted your approach, and what conversations you had
- Result – The concrete outcome (for example, “we agreed on a phased rollout, which increased adoption by X percent”) and one specific learning about stakeholder management you would reuse on a client project\
This maps well to EY-Parthenon’s focus on influence, client work and an investor style mindset.
Example outline 2: Resilience under pressure
Prompt: “Tell me about a time you were under significant time pressure.”
- Context – What was at stake, what was the deadline, who was relying on you
- Action – How you prioritised, delegated, communicated and protected quality. Mention at least one trade off you consciously made
- Result – What happened, plus what changed in your working style afterwards
How to prepare your stories
A practical approach:
- Build a bank of 7 to 10 stories that cover leadership, teamwork, conflict, impact, failure, learning and motivation.
- Tag each story with 1 or 2 EY-Parthenon values (for example collaboration, curiosity, integrity).
- Practice telling them out loud in 2 to 3 minutes, using CAR or STAR and focusing on what you did.
Many candidates find that using a behavioral question bank or a guided reflection worksheet forces them to dig deeper, find underused examples and sharpen the “Result” portion of each story. Used sparingly, those tools can save a lot of time.
EY-Parthenon Case Interview
EY-Parthenon cases are typically candidate led and emphasize structured thinking, commercial common sense, and clear, investor style trade off analysis. In final round or Super Day settings you may also face a group case or a written / slide based case that tests how you work with others and how you handle data under time pressure. Interviewers evaluate your structure, math accuracy, insight generation, and ability to communicate a practical recommendation.
Common industries: Expect a heavy mix of private equity and transactions style problems (commercial due diligence, value creation plans), plus corporate strategy cases in consumer and retail, healthcare, technology, industrials, and financial services. Many cases require comfort with competitive dynamics, market sizing, and basic value creation levers like pricing, mix, cost reduction, or growth initiatives.
Length: Single interviews are commonly around 45 to 60 minutes, with one case per interview. Super Days or assessment centers may involve two or three sessions back to back that include a group case or written case plus one or two live cases. Formats vary by region and practice, so confirm details with your recruiter for your specific office.
Interviewer or Candidate Led: Most EY-Parthenon interviews use a candidate led format, where you propose a structure and drive the problem-solving flow, but some interviewers will guide you more closely with targeted questions. Group and written cases naturally feel more interviewer led. You should be comfortable both steering a case conversation and responding to focused prompts, while thinking aloud and prioritizing quickly.
Quants and Exhibits: Expect quick mental math, simple financial arithmetic (margins, growth rates, payback), and exhibit interpretation. Many cases include revenue and cost tables, market forecasts, or customer and churn data. In some offices you may build or adjust a simple quantitative argument or back-of-the-envelope model under time pressure. Consistent mental math and exhibit drills are extremely helpful here: lots of otherwise strong EY-Parthenon candidates stumble on speed and accuracy when they face multi-step calculations under interview conditions.
