How EY-Parthenon interviews work
Your CV and cover letter are reviewed against specific criteria. Boutique firms often read applications personally. Clarity, specificity, and a coherent motivation for this firm matter from the first line.
Two to four rounds of case interviews combined with personal fit questions. Formats vary — some are interviewer-led, others candidate-led. Structure your thinking out loud and show you can hold a clear thread through complexity.
Final conversations with senior leaders, often less structured and more genuinely conversational. They're assessing whether they'd trust you in a room with a client. You're assessing whether this is the right firm for you.

Tips for your EY-Parthenon interview
Solo case prep has real limits. Social pressure, timing, and real-time redirection are fundamental to the actual interview experience. Find a practice partner and run through cases — the feedback from a real person is impossible to replicate alone.
Case interviews are the centrepiece of consulting recruitment. Learn profitability, market sizing, market entry, and M&A frameworks. More importantly, practice applying them to novel cases — not just repeating memorised structures. Interviewers score your thinking process, not pattern-matching.
Many candidates win the case and lose the offer. Fit interviews assess whether you're the kind of person clients and partners will trust. Preparation, genuine enthusiasm, self-awareness, and the ability to hold an engaging conversation all contribute to the decision.
Have clear, specific examples of leadership, problem-solving, teamwork, and commercial achievement. Practice telling each in under two minutes. These stories will recur across multiple rounds and interviewers.
Generic answers about "problem-solving" or "smart colleagues" are immediately recognizable and forgettable. Reference specific practice areas, published work, thought leadership, or alumni conversations that shaped your decision.
Consulting case interviews often involve quick calculations under pressure — percentages, growth rates, market size estimates. Practice doing these without a calculator until they feel automatic. Hesitation on basic maths undermines your credibility.
What a strong answer looks like
A well-structured STAR answer for a common EY-Parthenon interview question, showing exactly how to frame situation, task, action, and result.
Give me an example of when you challenged your own initial analysis.
I was working on a market entry analysis for a UK consumer brand considering expansion into Germany. My initial hypothesis, based on market size data, was that Germany was the strongest entry market in Europe.
I needed to finalise my recommendation within a week.
When I modelled unit economics more carefully, I found that the German retail market had significantly higher promotional spend requirements and lower margins than the UK baseline. I ran sensitivity analysis on three margin scenarios and found that under realistic conditions, Germany would take 4.5 years to reach payback — versus 2.1 years for the Netherlands, which had a smaller market but a more favourable trade structure. I updated my recommendation and documented the assumptions clearly so the client could stress-test them independently.
The client chose the Netherlands. At the one-year mark, the business was tracking ahead of the 2.1-year payback model. My manager used the analysis framework as a template for subsequent market entry work.
Frequently asked questions
What is the McKinsey Problem Solving Game or BCG online assessment?
Several leading consultancies use proprietary online assessments — McKinsey's Problem Solving Game tests decision-making and reasoning; BCG uses situational tests. They're not case interviews but act as early filters. Practice examples are widely available and worth completing before your actual assessment.
Do I need a business or finance background for consulting?
No. Consulting firms hire across all disciplines — STEM, humanities, social sciences, law. What they assess is how you think and communicate, not what you studied. Basic numeracy and commercial awareness are expected from all candidates regardless of background.
How many rounds are in a EY-Parthenon interview process?
Most top consultancies run 2–4 formal interview rounds, each typically including 2 case interviews plus a personal fit conversation. Total processes vary from 3 weeks to 2 months depending on the firm's recruiting cycle and the stage you apply at.
How do I prepare for a consulting case interview?
Start with frameworks (profitability, market entry, M&A), then move to applied practice with real cases. The most valuable prep is doing live cases with a practice partner who can give you real-time feedback — not just reading prep books or watching videos.
What does a consulting fit interview assess?
Fit or personal experience interviews assess your motivation for the firm, your leadership potential, how you work in teams, and whether you have the communication quality and client-presence consulting requires. Underestimating fit interviews is one of the most common reasons strong candidates don't convert.
