1. 006I give you two balance sheets and a P&L, but no cash flow statement. Build me the cash flow.Three statementsHardcase studyBig FourCorporate FP&A

   Say this

   I would build it indirect: start from net income, add back the non-cash charges I can see, then explain every balance sheet movement as either operating, investing or financing. Every line on the balance sheet has to be accounted for, and the check is that closing cash ties.

   Then walk it

   1. Take the difference in every balance sheet line, year on year. That list of deltas is the whole cash flow statement, just unsorted.
   2. Operating: net income, plus depreciation which I get from the movement in accumulated depreciation, plus other non-cash items, plus the change in receivables, inventory, payables and provisions. Assets up is a use of cash, liabilities up is a source.
   3. Investing: the change in gross fixed assets plus the depreciation charge gives me capex. Add any movement in investments or acquisitions.
   4. Financing: the change in borrowings, the change in share capital, and dividends paid which I back out of the retained earnings movement, opening retained earnings plus net income less closing retained earnings.
   5. Then the tie-out. The sum of the three sections must equal the change in the cash line. If it does not, I have missed a balance sheet movement, and the usual suspects are revaluation reserves, FX translation and a non-cash acquisition.
   6. On a real set of accounts I would also flag what the indirect method hides: it nets everything, so a company with big gross borrowings and repayments looks quiet. If I had the notes I would show gross.

   Where candidates lose it

   Trying to build it directly from receipts and payments. You do not have that data. Say the word 'indirect', anchor on retained earnings for dividends and accumulated depreciation for the charge, and narrate the tie-out at the end.

   Expect next

   • Where did the dividend number come from?
   • Your closing cash is off by 20. How do you find it?
   • Which balance sheet movements are not cash at all?
2. 014You have an hour with a set of accounts. What is your earnings quality checklist?Accounting policy and standardsHardcase studyRating agenciesBig Four

   Say this

   Six checks, in this order: cash conversion, receivable and inventory days, the gap between effective and cash tax, related-party transactions, auditor and policy changes, and the size of one-offs. Each one takes minutes and together they catch most of what goes wrong.

   Then walk it

   1. Cash conversion first. Cumulative operating cash flow divided by cumulative EBITDA over three to five years. Below about 70 percent on a mature business and I want an explanation.
   2. Then working capital in days, by line, over five years. Trends, not levels. Receivable days rising while revenue accelerates is the most common early warning in Indian mid-caps.
   3. Then tax. A persistent gap between the effective rate in the P&L and cash tax paid in the cash flow statement means profit is being recognised that the tax authority does not accept yet.
   4. Then related parties. Loans and advances to promoter entities, sales to group companies, royalty payments to the parent. This is where Indian governance failures concentrate, and the note is short enough to read fully.
   5. Then the housekeeping signals: auditor resignation or change, a qualification or emphasis of matter, a change in depreciation life or revenue policy, and any restatement.
   6. Then one-offs, and I would name the limitation in the same breath: add up 'exceptional' items over five years, because if they are exceptional every year they are operating costs with a friendlier label. None of this proves fraud either. It produces a list of questions for management, and the answers are the analysis.

   Where candidates lose it

   Reeling off ratios with no thresholds and no order. A checklist is only useful if you can say what number triggers concern and which check you run first. Cash conversion below 70 percent and rising receivable days are the two that earn their place.

   Expect next

   • Which of those six is the strongest single signal?
   • Walk me through a related-party note you would worry about.
   • How would you handle a company whose auditor just resigned?
3. 032How do you verify the validity of a client's pipeline to forecast revenue?Forecasting and budgetingHardcase studyHWHarris WilliamsInvestment Banking · Richmond · 2025

   Say this

   Test it against history rather than accepting the weightings. Take the pipeline as it stood 12 months ago, see what actually converted by stage, and apply those realised rates instead of management's. The gap between the two is your adjustment.

   Then walk it

   1. First, back-test. Pull the pipeline snapshot from four quarters ago, match it to closed business, and compute conversion by stage, by deal size and by sales rep. If stage-four deals converted at 45 percent while the model assumes 80, you have your answer.
   2. Second, check ageing. Deals that have sat in the same stage for three quarters are not pipeline, they are hope. I would strip or heavily discount anything past a normal cycle length.
   3. Third, look for hygiene problems: duplicate opportunities, deals with no close date or a close date that has been pushed four times, values entered as round numbers, and a bulge in the final quarter that mirrors the sales incentive calendar.
   4. Fourth, corroborate outside the CRM. Signed letters of intent, purchase orders, customer references, and for a diligence exercise, calls with two or three named prospects. Revenue that cannot be corroborated gets a haircut.
   5. Fifth, check coverage. Pipeline value over the target. Three times coverage on a 33 percent historical win rate is consistent; three times coverage on a 15 percent win rate is a miss waiting to happen.
   6. Then I would present it as a range: management case, back-tested case, and a downside using bottom-quartile conversion, with the bridge between them explained in one slide. The bridge is the deliverable, not the number.

   Where candidates lose it

   Accepting management's probability weightings and multiplying. Every CRM is optimistic near quarter end. The work is back-testing realised conversion by stage and stripping stale deals, and saying that is what gets you hired.

   Expect next

   • The sales head says your haircut is insulting. How do you handle it?
   • What if the CRM data only goes back two quarters?
   • How would this change for a business with three large customers?

4. 037Your forecast has missed by more than 10 percent three quarters running. What do you do?Forecasting and budgetingHardcase studyCorporate FP&ABusiness finance

   Say this

   Decompose the misses before changing anything. If the errors are all in one direction it is bias and the fix is process and incentives. If they are scattered it is variance and the fix is the model and the driver set. You cannot treat bias and variance the same way.

   Then walk it

   1. First, measure properly. Forecast error by line, by business unit, by owner, over eight quarters, with the sign preserved. Mean error tells you bias; mean absolute error tells you precision. Most organisations only track the second and then wonder why nothing improves.
   2. Second, separate the miss into volume, price, mix and timing. Three quarters of missing on timing is a completely different problem from missing on price, and the conversation goes to different people.
   3. Third, look at who submits the numbers and what happens to them when they are wrong. If sandbagging is rewarded and optimism is punished, you have designed the bias in, and no amount of model work will fix it.
   4. Fourth, fix the drivers. If revenue is forecast off a pipeline whose conversion assumption has never been back-tested, that is the error source. Replace judgement with realised rates wherever history exists.
   5. Fifth, change the output format. Move from a single number to a range with a named central case, and publish the forecast-versus-actual scorecard monthly with owners' names on it. Visibility corrects bias faster than any methodology change.
   6. The realistic expectation I would set: getting mean absolute error from 12 percent to 5 is a two- or three-quarter programme, not a month, and some businesses are genuinely unforecastable at that precision. Saying so is more credible than promising accuracy.

   Where candidates lose it

   Going straight to 'build a better model'. The most common cause is incentive-driven bias, not model error, and the diagnostic that separates them is whether the errors share a sign. Lead with that.

   Expect next

   • How would you present the bias finding to the business head who caused it?
   • What accuracy is realistic for a project business?
   • Would you change anyone's incentives?
5. 040Revenue beat budget by 6 percent but gross margin came in 200 basis points below. Explain it.Variance and management reportingHardtechnicalCorporate FP&ABusiness finance

   Say this

   Most likely you bought the revenue. Either you discounted, or the growth came from the lower-margin part of the portfolio, or input costs rose and you could not pass them on. A mix and price decomposition tells you which within an hour.

   Then walk it

   1. Run price, volume and mix on gross margin. That immediately separates discounting from mix, which are the two dominant causes and have completely different implications.
   2. Discounting shows up as an adverse price variance concentrated in specific customers or the last few weeks of the quarter. That is a commercial discipline problem and it repeats next quarter.
   3. Mix shows up as volume favourable and realisation down with list prices intact. If the growth came from the entry-level SKU or from a low-margin channel like a marketplace, margin falls by design and the right response may be to celebrate it.
   4. Input cost is the third: raw material, freight, power, or an unfavourable FX rate on imports. Check purchase price variance against standard and check whether a price increase was due and did not happen.
   5. Then the accounting-only explanations, which are worth eliminating early: absorption of fixed overhead over a different volume, an inventory provision taken into cost of goods sold, or a reclassification between cost of sales and operating expenses.
   6. The conclusion I would present: 6 percent more revenue at 200 basis points less margin on a 30 percent gross margin base is roughly flat gross profit in rupees. So the honest headline is that we grew revenue and earned nothing extra for it, and here is which of the four causes did it.

   Where candidates lose it

   Reporting the revenue beat as good news. Convert both movements into rupees of gross profit before you conclude anything. And do not offer a cause without the decomposition, because guessing between discounting and mix is a coin flip.

   Expect next

   • How would you stop end-of-quarter discounting?
   • What if the growth is all in the new low-margin channel?
   • How does fixed overhead absorption distort this?
6. 051A customer wants 20,000 units at a price below your full cost. Do you take the order?Unit economics and costingHardtechnicalCost accountingBusiness finance

   Say this

   If the price is above variable cost and you have spare capacity, it adds profit, so on the arithmetic yes. But I would only recommend it if the order does not displace better business and does not reset the price for everyone else.

   Then walk it

   1. The arithmetic first. Full cost 100, of which 70 variable and 30 absorbed fixed. Offer price is 85. Every unit adds 15 of contribution, so 20,000 units adds 3 lakh of profit, because the fixed 30 is being paid anyway.
   2. So the accounting answer is clear, and the reason candidates get this wrong is they compare price with full cost. Fixed cost is irrelevant to an incremental decision unless the order causes it to change.
   3. Then the conditions. Is there genuinely spare capacity, or does this displace full-price volume? If it displaces, the relevant cost includes the contribution you give up, and the answer usually flips.
   4. Does it trigger a step cost? Overtime, a second shift, additional tooling, extra freight or a special packaging run all count as incremental cost even though they look fixed on the standard cost sheet.
   5. Then the commercial risks, which is where finance earns its seat. Price leakage to existing customers, grey-market resale back into your own market, most-favoured-customer clauses, and the precedent that this buyer now expects 85 forever. In an export or institutional channel those risks are managed by segmentation and contract terms.
   6. So my recommendation would be: accept as a contained one-off with a defined volume cap, different packaging or channel, and a written statement that it is not a list price change. And I would name the margin dilution it will show in the monthly pack so nobody is surprised.

   Where candidates lose it

   Rejecting it because the price is below full cost. That is the textbook error the question exists to catch. But saying yes with no conditions is the other half of the trap, because the real answer includes displacement and price-leakage risk.

   Expect next

   • What if you are already at full capacity?
   • How would you stop the price leaking to existing customers?
   • Where does the contribution show up in the monthly variance pack?
7. 052Here are a few figures about an airline. Work out what it should charge for a ticket, and ask me for anything else you need.Unit economics and costingHardcase studyBain CapitalGeneralist · Boston · 2024

   Say this

   I would build cost per available seat kilometre, convert it to cost per seat on the route, divide by the load factor to get cost per sold seat, then add a margin. Before that I need four things: seats per aircraft, sector length, load factor and the split of fixed versus variable cost.

   Then walk it

   1. The structure: total operating cost per flight divided by seats gives cost per seat. Divide by the expected load factor, say 80 percent, and cost per sold seat rises by 25 percent. That step is the one candidates skip and it is the largest single adjustment.
   2. A worked illustration. If a flight costs 15 lakh to operate with 180 seats, that is about 8,300 per seat. At 80 percent load, cost per sold passenger is about 10,400. Add a 10 percent margin and the average fare needs to be around 11,500.
   3. Then I would ask what I am solving for, because the answer differs. The average fare needed to break even on the route is one question; the price of the marginal seat two days before departure is another, and there the only relevant cost is a few hundred rupees of fuel, catering and commission.
   4. That marginal-cost logic is why airlines use dynamic pricing. The same seat is worth 3,000 in a seat-sale ten weeks out and 18,000 to a business traveller on the day, and the fixed cost of the flight is sunk either way.
   5. The inputs I would keep asking for: fuel as a share of cost, aircraft ownership or lease cost per hour, crew and airport charges, ancillary revenue per passenger, and the competitive fare on the route. Ancillary matters enormously for a low-cost carrier; baggage and seat fees can be 15 to 20 percent of revenue.
   6. And the conclusion I would state: cost tells you the floor, competition and willingness to pay tell you the price. In a market with a dominant low-cost competitor, the cost-plus number is often simply unachievable, and then the decision is whether to fly the route at all.

   Where candidates lose it

   Dividing cost by total seats and quoting that as the fare. You must divide by load factor. The second trap is not asking questions: the interviewer deliberately gave you partial data, and the questions you ask are half of what is being marked.

   Expect next

   • What is the marginal cost of the last seat sold?
   • How would ancillary revenue change your answer?
   • A competitor prices 20 percent below your floor. What do you do?

8. 053How would you build a loyalty programme for a rideshare business, and how would you know if it worked?Unit economics and costingHardcase studyJane StreetProduct and Strategy · New York · 2026

   Say this

   Treat it as an investment with a measurable return, not a marketing scheme. The programme costs you contribution per redeemed reward and buys incremental trips from riders who would otherwise switch. If you cannot measure the incremental trips, do not launch it.

   Then walk it

   1. Start with the economics of one trip: fare, driver payout, payment and support cost, leaving a contribution of maybe 15 to 20 percent of fare. Every rupee of reward comes straight out of that, so the programme has to move behaviour, not just reward it.
   2. Segment before designing. The high-frequency commuter is already loyal and paying them is pure margin leakage. The target is the mid-frequency multi-app user, four to eight trips a month, who is genuinely switchable. That is where incremental trips live.
   3. Design levers: earn rate, tiers with a threshold just above the target segment's current frequency, rewards that cost you less than they are worth to the rider such as priority matching or a waived cancellation fee rather than cash discounts, and expiry to cap the liability.
   4. Then the two supply-side pieces people forget. Loyalty that promises faster pickup requires driver density, so the reward may need a driver-side incentive to be deliverable. And a growing points balance is an accounting liability under Ind AS 115, deferred revenue for unredeemed points.
   5. Measurement is the whole answer: run it as a geo or user-level randomised holdout. Compare trips per user, retention and contribution per user between treated and control. Without a control group you will credit the programme with trips it did not cause, which is how most loyalty programmes are declared successful.
   6. The kill criteria I would write down before launch: incremental contribution per rupee of reward cost above one within two quarters, and no more than a set share of rewards going to users whose frequency did not change. If it fails either, shut it.

   Where candidates lose it

   Designing features without unit economics or a control group. The interviewer wants contribution per trip, a target segment that is actually switchable, and a holdout test. Cash discounts to your existing best customers is the answer that fails.

   Expect next

   • How would you size the incremental trips before launching?
   • What is the accounting liability for unredeemed points?
   • Would you fund it from the driver side or the rider side?

9. 058I give you a list of possible projects with their values and their costs, and a fixed budget. How do you choose?Capital budgetingHardcase studyBridgewater AssociatesGeneralist · New York · 2025

   Say this

   Rank by value per rupee of the constrained resource, not by absolute value. Compute the profitability index, NPV divided by the capital required, take them in descending order until the budget runs out, then check the combinations near the cut-off because the greedy answer is not always optimal.

   Then walk it

   1. Profitability index is present value of inflows over the initial investment, or equivalently one plus NPV over investment. Anything above one adds value; ranking by it maximises value per unit of the scarce resource.
   2. A quick illustration. Budget 100. Project A: NPV 30, cost 60, index 0.50. Project B: NPV 18, cost 40, index 0.45. Project C: NPV 16, cost 40, index 0.40. Greedy picks A then B for 48 of NPV on 100 spent. Picking B and C gives 34. So A plus B wins, but you only know that because you checked.
   3. The reason you check is indivisibility. Projects cannot be taken in fractions, so this is a knapsack problem, and greedy ranking can leave budget stranded. With a handful of projects, enumerate the combinations; with many, solve it as an integer programme, which Excel Solver will do.
   4. Then the constraints that make it a real decision rather than an arithmetic one: mutual exclusivity where two projects do the same thing, dependencies where B requires A, and non-capital constraints like scarce engineering time, which may be the binding resource rather than money.
   5. Then the multi-period version. A project may be delayable, so the question becomes which projects this year and which next, and a one-year delay on a positive-NPV project has a real cost you should quantify rather than assume away.
   6. And I would flag the strategic overlay: some low-index projects are mandatory, safety, regulatory or IT security, so they come out of the budget before ranking begins. Pretending everything competes on index is how compliance projects get deferred until they become a crisis.

   Where candidates lose it

   Ranking by NPV alone, which strands capital, or by IRR, which ignores scale. The word the interviewer wants is profitability index, followed immediately by the acknowledgement that indivisibility makes greedy ranking imperfect.

   Expect next

   • What if two of the projects are mutually exclusive?
   • What if the binding constraint is engineers, not money?
   • How would you handle a project you can delay by a year?

10. 074You inherit a model from someone who left last week and the CFO wants to use it on Monday. How do you audit it?Modelling, Excel and dataHardcase studyFinancial modellingBig Four

    Say this

    Work from the outside in. First sanity-check the outputs against reality, then trace the three or four numbers that drive them, then stress-test rather than read every cell. You cannot audit 40,000 formulas by Monday, so you audit the ones the answer depends on.

    Then walk it

    1. Start with the outputs. Does revenue growth, margin and cash flow look plausible against history and against the sector? An implied 45 percent EBITDA margin on a distribution business tells you more in ten seconds than an hour of cell tracing.
    2. Then the structural checks: does the balance sheet balance, does the cash flow tie to the cash movement, does historical data reconcile to the published accounts. Any break here and nothing downstream is trustworthy.
    3. Then mechanical scanning. Use formula view or a spreadsheet audit tool to find hard-coded constants inside formulas, inconsistent formulas within a row, broken links to external files, circular references and unintended ranges. A row that is consistent for eleven periods and different in the twelfth is exactly what you are hunting.
    4. Then stress tests, which are the fastest way to find logic errors. Set revenue growth to zero, set it to 50 percent, set price to nil. If EBITDA does not move sensibly, or the balance sheet breaks under a stress, you have found a hard-code or a broken link.
    5. Then trace the top three value drivers back to their source, and only those. For a DCF that is usually WACC, terminal growth and the revenue build. Verify each against a document, not against another cell in the same model.
    6. And I would tell the CFO on Friday what I had and had not verified, in writing, with a short list of numbers I do not yet trust. Presenting an unaudited model as clean is the career risk here, not the model itself.

    Where candidates lose it

    Saying you would check every formula. There is not time and it is the wrong method. Outputs first, structural checks, mechanical scan for inconsistencies, then stress tests. And say you would disclose what you could not verify.

    Expect next

    • What is the fastest way to find a hard-coded number?
    • You find an error that changes the answer 20 percent. What do you do?
    • How would you hand this model on properly?
