Bike Share Bid: A city's bike share, sold for a lump sum
Written to Oliver Wyman's six steps and its advice to treat the interviewer as your client: you set a bid for a public concession, and the interviewer hands you data as you ask for it. The full version is City Bike Share Concession, our library case. Oliver Wyman (opens in a new tab), read
1Step 1: Read the case
A US city wants to hand its public bike share, 5,000 stations, to a private operator for fifteen years in exchange for one upfront payment. The operator keeps all ride revenue and pays to upgrade and run the system. Your client, a mobility company, asks how much it should bid.
2Step 2: Ask clarifying questions
Open a question to hear the interviewer's answer.
What exactly does the winner get?
Interviewer: Fifteen years of operating rights. The operator maintains the equipment, runs the system and keeps all ride revenue.
How are rides priced?
Interviewer: A flat fare per ride in three zones: downtown, an urban ring and the suburbs. Assume the zone fares stay fixed for the whole term.
Do we know how much the bikes are used?
Interviewer: Yes: the share of stations and the average daily rides per station in each zone. I will show you the table when you are ready for numbers.
What will it cost us to run?
Interviewer: A one-time upgrade of bikes, docks and technology, then yearly maintenance, labor and technology operations. You will get the breakdown after your structure.
Should we assume growth, or a required return?
Interviewer: Keep rides and costs flat for fifteen years. No discount rate is given; if you use one, say so.
Why is the city selling?
Interviewer: It loses money running the system, mostly on labor and deferred maintenance.
3Step 3: Structure your answer
Take two minutes. Treat the interviewer as your client: lay out how you would value the fifteen-year concession and turn that value into a bid, then say where you would start.
2:00
Show what a strong structure covers
Plays the goal back: a bid price for fifteen years of operating rights, not a yes or no on the deal (Oliver Wyman's first step, pinpoint the issue).
Revenue by zone: stations, rides per station per day, fare per ride and days a year, plus extra income such as advertising or passes.
Costs in two parts: the one-time upgrade, paid once, and the yearly running costs.
Value over the term: yearly profit times fifteen years, minus the upgrade, and a word on discounting cash that arrives later.
The bid: below that value, with a margin for risk and a view on rival bidders.
Risks to test: ridership, fixed fares, maintenance surprises and what the city requires when the term ends.
Starts with revenue by zone, the biggest and least certain number.
4Step 4: The interviewer's next question
The interviewer shows the usage table: downtown has 10% of stations, 30 rides a day each and a fare of 4; the urban ring 25%, 18 rides and 2.5; the suburbs 65%, 8 rides and 1.5 (fares in dollars). Assume 365 days a year. What is annual ride revenue?
Show what a strong answer does
Works zone by zone: 500 stations × 30 × 4 × 365 is about 21.9 million; 1,250 × 18 × 2.5 × 365 about 20.5 million; 3,250 × 8 × 1.5 × 365 about 14.2 million; about 56.7 million in all. It notes that downtown earns the most from a tenth of the stations, then asks for costs before it talks about a bid.
Flour costs rose 18% on a $4M flour bill, and prices went up 3% on $20M of sales. How much margin did Harbor lose?
Your answer
Flour went up by about $720K and the price rise brings in $600K, so the net hit is roughly $100K.
What worked
Split the change into a cost side and a price side before adding them up.
Could improve
$720K minus $600K is $120K, not $100K: state the exact net before rounding.
Model answer
Flour: 18% of $4M is $720K more cost. Price: 3% of $20M is $600K more revenue. Net margin loss: $120K.
Next time, say this
Cost is up $720K and price brings back $600K, so Harbor loses $120K of margin.

Worked: Autism Digital Device, in Oliver Wyman's six steps
An Indian startup has built a tablet-based therapy product for autistic children (interactive videos, audiobooks and games) that cuts the need for in-person therapy by a third. It sells in English across India against two or three similar products, and asks Oliver Wyman how to price it before launch. The case asks for a pricing approach, a comparison with rivals and a recommendation. Read the official case (opens in a new tab)(read )
How you might work it is ours, not Oliver Wyman's answer key.
1
Pinpoint the issue
Play the goal back: a launch price and a pricing model, not whether to launch. Ask what the startup values more, reach or profit; who pays (families, since public health insurance does not cover it); and how often a child would use it.
2
Break it down
Three questions, each giving a bound: what the product saves a family, what rivals charge, and what it costs to serve one user. Sketch them side by side on paper and ask for the data each one needs.
3
Pick an approach
Say how the three fit together: savings set the ceiling, cost sets the floor, and rivals show where in that range families will buy. State the assumptions out loud, such as the share of families with a tablet who use it in English.
4
Analyze the issues
Therapy costs about INR 300,000 a year and the product replaces a third, so a family saves about INR 100,000: the ceiling. Rivals charge INR 50,000 to 75,000, the cheapest with fewer features. Delivery costs about INR 10 billion a year with small variable costs, so cost per user depends on how many families you reach.
5
Use numbers
Size the users before you divide: filter the ten million children by income, tablet access and English, then take a realistic share against rivals and doctors. Show the swing: two million paying families puts cost near INR 5,000 each, half a million near INR 20,000. Say which you believe and why.
6
Make a recommendation
Open with one price and one model, then the three reasons (the ceiling, where rivals sit, your floor) and the first risk to test, in under a minute. Whether you undercut the cheapest rival to reach more families is your call; defend it with the user count you assumed.

The Oliver Wyman interview process, and what trains each step
1
Online test, where your office uses one
Oliver Wyman's Brazil and Mexico recruiting page lists a 26-question, 50-minute online test in English after the application, covering critical reasoning, problem solving, data sufficiency and integrated reasoning. Its global interview preparation page names no test, so follow your invitation.
Oliver Wyman's name for its fit interview: a conversation about your accomplishments, experience, interests and career goals, which also gives you time to ask about the firm.
An interactive exercise, often based on real client problems. Oliver Wyman's six steps: pinpoint the issue, break it down, pick an approach, analyze the issues, use numbers, and make a recommendation. It tells you to treat the interviewer as your client, who wants you to solve the problem and can help you do so.
After a 15-minute fit interview with no case, two rounds of two case interviews each, partly in English. The whole process is virtual and each stage decides whether you move on. Oliver Wyman's other careers pages give no round count, so ask your recruiter.
Written case, in some final rounds (candidate reports)
None of the Oliver Wyman careers pages checked for this page describes a written case. Candidates report one in some offices' final rounds: about 30 minutes alone with a packet of exhibits, then about 30 minutes presenting and defending a recommendation. Confirm it from your invitation.
Missing from Oliver Wyman's pages: how many interview rounds there are outside Brazil and Mexico, how long a case interview runs, whether it is interviewer-led or candidate-led, how answers are scored, whether there is a written case, and whether other offices use an online test.
13 Oliver Wyman-style interview questions
In our words, not Oliver Wyman's, grouped by its six steps, with what a strong answer does. Several lean to financial services and public concessions; do Oliver Wyman's own five cases too, in the table above.
Step 1: Pinpoint the issue
Oliver Wyman: ask clarifying questions and summarize the situation in your own words.
1A regional insurer's motor policies grew by a tenth last year, but the motor line now loses money. The CEO asks what to do. What do you clarify, and how do you play the problem back?
What a strong answer does: Restates the goal as profit on the motor line, asks the two or three questions that change the plan (claims cost or pricing, which customers grew, by when) and then stops asking.
2A city is offered a lump sum to hand its airport parking to a private operator for twenty years. What do you need to know before you structure?
What a strong answer does: Asks what the operator gets and owes (the term, pricing freedom, upkeep, what happens at the end), how the city will judge offers, and whether a required return is given.
Oliver Wyman: are there smaller problems inside the big one? Diagram your ideas.
3A bank's credit card business lost money for the first time. Structure the problem.
What a strong answer does: Splits profit into revenue (interest, fees, interchange) and costs (funding, credit losses, rewards, operations), then says which branch it would test first and why.
4A private equity fund asks whether to buy a chain of veterinary clinics. Lay out your issue tree.
What a strong answer does: Covers the market, the chain's position and profit, the price and the exit, and ends each branch with the data that would answer it.
Oliver Wyman: show why your approach beats the alternatives, and state your assumptions.
5Estimate the yearly pet insurance premiums paid in a country of 60 million people. Which route do you take, and why?
What a strong answer does: Picks one route (households, pet owners, the share insured, the average premium), says why it beats the alternative, states each assumption and flags the one that swings the answer most.
6A digital bank must price a new savings account. Do you start from its costs, rivals' rates or what customers value?
What a strong answer does: Names all three, picks the one that decides it (rivals' rates, for a product customers compare easily), and agrees it with the interviewer before calculating.
Oliver Wyman: ask for the data you need, take a creative leap when stuck, and be careful with simple calculations.
7A lender's loan book is 400 million. Defaults rose from 2% to 3.5% a year, and it recovers 40% of a defaulted loan. How much more does it lose a year?
What a strong answer does: Finds the extra defaults (1.5% of 400 million is 6 million), takes off the 40% recovered (3.6 million lost), then says what that means for the lender before asking about its profit.
9Your math says a concession is worth 25 million, but the city wants 40. What now?
What a strong answer does: Rechecks the inputs behind the gap, then takes a creative leap (more revenue, lower costs, a shorter term) and says which would close it and how sure it is.
11A bank can close a third of its branches or move them all to a smaller format. What do you recommend?
What a strong answer does: Picks one with the number that decides it (costs saved against deposits at risk), says what would change the call, and what to pilot first.
Oliver Wyman: your background, interests, career objectives and accomplishments, then your questions.
12Walk me through an accomplishment you are proud of.
What a strong answer does: Picks one with a result you can measure, says what you did yourself rather than the team, and links it in one sentence to the work you want to do.
13Why Oliver Wyman, and what would you like to ask us?
What a strong answer does: Names one specific part of Oliver Wyman (a practice, its financial services work, its job simulation) tied to your goals, then asks a question its website does not answer.

An Oliver Wyman prep plan, day by day
The order follows Oliver Wyman's own pages; the timing is our suggestion.
Days 1 and 2
Read Oliver Wyman's own guidance
Read the six things a case tests and the six steps, and check from your invitation which steps you face (an online test, if you apply in Brazil or Mexico).
Urban Grocers first, then the four medium cases. Answer each question out loud and on paper before you reveal the sample answer, and note which evaluation criteria you missed.
You have now seen Oliver Wyman's answers, so run fresh cases with an AI interviewer, starting with a public concession. Add one math and one chart rep a day.
How should I prepare for the Oliver Wyman case interview, and which free resources should I use?
Start with Oliver Wyman's own interview preparation page: its six-step case method and five free practice cases with sample answers (Urban Grocers, Supermarket Pharmacy, Dairy Farm, Autism Digital Device and Poseidon Water Park). Then train each step your invitation names: an online test where your office uses one, the conversational interview, the case interviews and, if your final round has one, a written case. On Road to Offer a free account includes 1 full AI-graded case, such as City Bike Share Concession, a math-heavy valuation case; Pinecrest Cold Storage and Larchfield Pet Cover are worked cases with a model answer for every question and need no account. Firm-style cases are practice cases written for Road to Offer or adapted from university consulting club casebooks, not the firm's own cases.
Where can I practice Oliver Wyman-style case interviews for free?
Oliver Wyman's five practice cases on its interview preparation page are free, with a sample answer for each question and no account. On Road to Offer, 3 math-heavy library cases are matched to Oliver Wyman's case types; you run them out loud with an AI interviewer or step by step, and your first full case is free with a free account. The sample case on this page runs in your browser with no account. Pinecrest Cold Storage (a warehouse investment decision) and Larchfield Pet Cover (a pet insurer's market entry) are free to read with a model answer for every question, no account.
What practice cases does Oliver Wyman publish, and how should I use them?
Five, free on its interview preparation page with no sign-up: Urban Grocers (marked easy), then Supermarket Pharmacy, Dairy Farm, Autism Digital Device and Poseidon Water Park (marked medium). Do Urban Grocers first. For each question, answer out loud and on paper before you press reveal, then compare your answer with Oliver Wyman's sample answer and the evaluation criteria it lists. Older names you may see elsewhere no longer open: WumbleWorld and Aqualine now land on the general careers page, and Oil Gas Price Strategy returns a 404.
What happened to the WumbleWorld and Aqualine cases?
They are no longer on Oliver Wyman's site. The India and Nordics copies of its interview preparation page still link them, but both links now open the general careers page, and the Oil Gas Price Strategy case page returns a 404. The five live cases are Urban Grocers, Supermarket Pharmacy, Dairy Farm, Autism Digital Device and Poseidon Water Park.
Does Oliver Wyman see or score my answers to its practice cases?
No. There is nothing to submit: each question on the case page has a button that reveals Oliver Wyman's sample answer, and most questions list the criteria an interviewer would evaluate, so you grade yourself. Write your answer down before you reveal, or you will grade the sample answer instead of yours.
Does Oliver Wyman have a Forage job simulation?
Yes. Oliver Wyman's students page links one virtual job simulation on Forage, Financial Services: Climate Change, in which you help a bank set net-zero targets for its energy lending. Forage lists four self-paced tasks with example answers from Oliver Wyman's team, about four to five hours, and no grades. It shows the kind of financial services work Oliver Wyman does; it is not a case interview.
Does Oliver Wyman have an online test?
Some offices do. Oliver Wyman's Brazil and Mexico recruiting page lists an online test of twenty-six questions in 50 minutes, in English (critical reasoning, problem solving, data sufficiency and integrated reasoning), with instructions emailed the day before. Its global interview preparation page names no test, and candidate reports for other offices differ, so follow your invitation. Road to Offer has no Oliver Wyman test simulator: our online test guide covers the formats candidates report, and the case math and chart drills train the numerical skills.
How many interview rounds does Oliver Wyman have?
Oliver Wyman publishes a count only for Brazil and Mexico: an online test, a 15-minute fit interview in English with no case, then two rounds of two case interviews each, partly in English. The whole process is virtual, every stage decides whether you move on, and if you are turned down at the fit interview you wait one year to reapply. Its other careers pages give no round count, so ask your recruiter.
Is the Oliver Wyman case interview candidate-led or interviewer-led?
Oliver Wyman uses neither label. Its interview preparation page calls the case an interactive exercise and tells you to treat the interviewer as your client, who wants you to solve the problem and can help you do so. Expect to propose the structure, ask for the data you need and drive to a recommendation while the interviewer steers. Its practice cases run as a series of set questions, closer to an interviewer-led case.
Is the Oliver Wyman case interview written or spoken?
Oliver Wyman describes a spoken, interactive case, and its tips tell you to put your first thoughts on paper and diagram your ideas while you talk. None of its careers pages describes a written case; candidates report one in some offices' final rounds, about 30 minutes with a packet of exhibits and then about 30 minutes presenting, so confirm it from your invitation.
What behavioral questions does Oliver Wyman ask?
Oliver Wyman calls its fit interviews conversational interviews: questions about your accomplishments, experience, interests and career goals. It publishes no question list; candidates report why consulting, why Oliver Wyman, walk me through your CV, and stories about leading a team, persuading someone who disagreed and a failure. Prepare one story for each and say it out loud; Road to Offer's fit practice asks Oliver Wyman questions with follow-up probes, 1 session free with a free account.
