Free sample case: client conversation

A Oliver Wyman-style case you can try now

Oliver Wyman says to treat the interviewer as your client and work together through a six-step approach. The sample case follows those steps.

Step 1. Read the case

Harbor Savings: close 30 branches?

The interviewer plays the client

Your client is Harbor Savings, a regional retail bank with 120 branches. Management wants to close the 30 branches that cost the most to run and move their customers to the mobile app and nearby branches. The CEO asks you whether the bank should do it. Treat the interviewer as your client and work the problem together.

An original, fictional practice case written by Soreno in a Oliver Wyman-style format. It is not a Oliver Wyman interview question. Everything stays in your browser.

Step 2. Ask clarifying questions

Oliver Wyman tells candidates to treat the interviewer as the client. Ask what you need to understand the objective and the numbers, then summarize it back in your own words.

Step 3. Structure your answer

Summarize the situation in two sentences, then lay out how you would break the problem down. Take two minutes, write it, then say it out loud to your client.

What the Oliver Wyman interview looks like

Here is what Oliver Wyman says about its interviews on its own careers pages, and what it does not publish.

What Oliver Wyman says

  • Interviews are a mix of conversational interviews (your background, interests and goals) and case interviews, which are interactive exercises on how you approach and evaluate problems, often based on real client challenges. Oliver Wyman: Interview preparation.
  • Its advice starts with treating your case interviewer as your client: they want you to solve the problem and can help, so work together. Oliver Wyman: Interview preparation.
  • It describes six steps for a case: pinpoint the issue (clarify and summarize), break it down, pick an approach and state assumptions, analyze the issues, use numbers carefully and make a recommendation that ties the findings together. Oliver Wyman: Interview preparation.
  • The page links six sample cases (Urban Grocers, Supermarket Pharmacy, Dairy Farm, Autism Digital Device, Oil Gas Price Strategy and Poseidon Water Park) for practice. Oliver Wyman: Interview preparation.
  • In its Brazil and Mexico campus recruiting, the process is an online test of 26 questions in 50 minutes, a 15-minute fit interview and then two rounds of case interviews, two per round. Oliver Wyman: Latin America entry-level.

What Oliver Wyman does not publish

  • how many rounds there are or how long each interview is. The Latin America page gives numbers for that region only.
  • who leads the case. Oliver Wyman's pages do not say whether the interviewer or the candidate drives it. The sequence of questions in the sample case is Soreno's practice style, not an Oliver Wyman statement.
  • scoring criteria, pass marks or how the interviews are weighted.

How Soreno's AI interviewer maps to Oliver Wyman practice

These are features that exist in the Soreno app today. They practice the skills Oliver Wyman's guidance describes. They do not reproduce its questions or scoring.

  • 1

    No Oliver Wyman-specific interviewer style

    Soreno has McKinsey, BCG, Bain, strict and coach interviewer styles and a default style, but no Oliver Wyman style. Use the default interviewer for a balanced conversation, or the coach style for hints while you learn the six steps.

  • 2

    Interviewer-led or interviewee-led

    You choose the interview style in Settings. Interviewer-led means the AI asks a sequence of questions; interviewee-led means you drive the case and decide what to analyze. Try both, because firms and interviewers differ.

  • 3

    Exhibits and math checks

    The AI interviewer shows exhibits, asks you to walk through calculations and checks your arithmetic. Timed drills cover case math, market sizing and structuring.

  • 4

    A scored report that quotes you

    After each session you get feedback that points to moments in your own answer and a next-step plan. Recorded sessions also get filler-word and eye-contact analysis.

You set the interviewer personality and the interview style in Settings, under Interview preferences. Soreno does not simulate Oliver Wyman's own practice cases, tests or tools, which the firm publishes for free where it offers them. Use them alongside Soreno.
