Financial Analysis interview preparation
The three statements, working capital, ratios, forecasting, variance analysis, costing, capital budgeting, valuation and the modelling and Excel work that fills the day, plus the fit questions about why this seat. Every question is either traced to a named firm from a public candidate report, or tagged at desk level when we could not trace it — we do not invent attributions.

053How would you build a loyalty programme for a rideshare business, and how would you know if it worked?Jane 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
- 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.
- 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.
- 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.
- 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.
- 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.
- 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?
