Congrats on the interview. For this team, focus on:
- Profitability / cost‑reduction, growth strategy, and basic commercial‑due‑diligence / value‑creation cases (is a deal attractive, where to create value, key risks).
- Clean, MECE structures, quick and accurate math, and the ability to translate analysis into a simple, actionable recommendation.
- Fit questions around teamwork, handling pressure, and “Why consulting / Why EY‑Parthenon Germany?”, with 2–3 concrete stories.
Typical process is a few rounds of mixed fit + candidate‑led business cases; they care less about fancy frameworks and more about clear thinking and communication.
