Bain & Company (BCN) interview questions and answers

Guesstimates

According to reports, your assumptions and structure matter more than the exact number.

  1. 1.Guesstimate: how many vada pavs are sold in Mumbai in a day?

    What they're checking
    Structured estimation.
    How to answer
    Population (~2 crore) x people who eat vada pav (%) x how often per week / 7. Or from supply: stalls x daily sales. Check with both and keep stating assumptions.

  2. 2.What do you do if one of your guesstimate assumptions turns out wrong?

    What they're checking
    Flexibility.
    How to answer
    Accept the interviewer's data, recalculate only that part, and say how much the answer changed - don't start over.

Cases and business basics

  1. 3.A private equity client wants to buy a chain of dental clinics - what would you look at?

    What they're checking
    BCN supports private equity.
    How to answer
    The market (size, growth), competition, the chain's performance (revenue per clinic, margins), risks (dentists leaving, regulation), and the deal's value. Where you would get data for each part.

  2. 4.An e-commerce company's repeat customers are falling - why?

    What they're checking
    A customer case.
    How to answer
    Break down the customer journey: product/price, delivery, returns, app experience, competition. Find from data which cohort is falling, then form a hypothesis.

  3. 5.How do you calculate the break-even point?

    What they're checking
    Business maths.
    How to answer
    Fixed cost / (price per unit - variable cost per unit) = the units at which there is neither profit nor loss. Give a small example.

  4. 6.Apply Porter's five forces to the food delivery industry.

    What they're checking
    Using a framework properly.
    How to answer
    Threat of new players, restaurants' power, customers' power (easy to switch), substitutes (going yourself, cooking), and rivalry. The 'so what' of each force.

Analyst skills

  1. 7.What does a BCN Analyst do day to day?

    What they're checking
    Understanding the role.
    How to answer
    Industry research, cleaning and analysing data (Excel), making charts and slides, and quick answers to case teams' questions. Both research and data.

  2. 8.What is the difference between VLOOKUP and INDEX-MATCH (or XLOOKUP) in Excel?

    What they're checking
    An analyst's basic tool.
    How to answer
    VLOOKUP looks only in the left column and returns from the right, with a fixed column number. INDEX-MATCH/XLOOKUP work in any direction and don't break when columns are added.

  3. 9.What is an 'action title' on a PowerPoint slide?

    What they're checking
    Consulting communication.
    How to answer
    A title that states the slide's main finding in one line - 'Online sales doubled in 2 years' - not just 'Online sales'.

  4. 10.What is your strategy for an online test with negative marking?

    What they're checking
    Negative marking has been reported.
    How to answer
    Easy questions first, guess only when you can eliminate 2 options, and don't spend too long on any one question.

Fit

  1. 11.Why BCN, and why do you like a particular sector (such as financial services)?

    What they're checking
    Reports mention being asked the reason for a sector choice.
    How to answer
    BCN's mix of research + data, and a real reason for the sector - an internship, a project or your studies. If it differs from your background, explain the bridge.

  2. 12.What was your own contribution in the leadership role on your resume?

    What they're checking
    Resume deep dive.
    How to answer
    Your own work, not the team's - what you decided, what you did, and the result (with numbers).
