EY Parthenon SaT - Strategy and Operations Consultant

Hi there,

I have an interview with EY Parthenon SaT team for a Strategy and Operations Consultant position in Europe (DACH) including a case interview. Any tips for what the case is likely to be and how best to prepare for the interview as a whole would be very welcome. I've so far done about 20 live cases with a lot of market entry style cases. The interview will be a 30 minute HR interview, a 30 minute case study with the manager, and then a meeting with the partner. Any tips for the HR part and the meeting with the partner would also be much appreciated.

Thanks

Hi there,

Congrats on the interview! Your preparation so far with 20 live cases, especially market entry cases, is a great start. For EY-Parthenon’s SaT team, you can expect cases that align closely with their work—commercial due diligence, growth strategy, and M&A-related cases. While market entry is relevant, also make sure you’re comfortable with profitability, commercial due diligence (CDD), and private equity-style cases (e.g., “Should a PE firm acquire this company?”).

For the case interview with the manager:
    •    Be structured and hypothesis-driven – Managers at EY-Parthenon appreciate clear frameworks but also expect you to adapt them based on the case details.
    •    Quant skills matter – Be quick with mental math and comfortable interpreting financials, as SaT cases often involve revenue projections, market sizing, and valuation elements.
    •    Synthesize clearly – Always wrap up with a strong conclusion that ties insights back to the client’s strategic goals.

For the HR interview:
    •    Expect behavioral questions around teamwork, leadership, problem-solving, and why EY-Parthenon specifically.
    •    Have clear STAR (Situation, Task, Action, Result) answers ready, especially around experiences that highlight analytical thinking, adaptability, and collaboration.
    •    Know your motivation for strategy consulting and EY-Parthenon’s SaT focus—HR will want to see that you understand their positioning versus competitors.

For the partner interview:
    •    This is often more conversational and focused on your fit for the firm and industry insights.
    •    Expect high-level strategic questions like “What are the key drivers of M&A activity in [DACH industry] right now?” or “How would you assess a company’s market attractiveness?”
    •    Be prepared to discuss your past experience in a way that aligns with EY-Parthenon’s work—partners look for client-ready professionals who can think critically about business problems.

I’ve been with EY-Parthenon for six years now, so I can definitely help with your finalising your prep and refining a few final bits - feel free to reach out!

Best,
Evelina
