A · Professional problem solving and implementation4
- How would you design a platform where operations staff build campaigns and game mechanics themselves? How do you abstract campaigns, mechanics, rules, and features into configurable parts, and how do you keep a configuration correct once it goes live?
- How should coupons, discounts, and flash sales integrate with a trading system without slowing the core transaction flow? How would you calculate, combine, and reconcile discounts?
- A subscription product includes trials, renewals, grace periods, refunds, and family sharing. How would you design entitlement checks so several services receive consistent, traceable results?
- A usage-based API product must combine request events from multiple regions into customer bills and allow later corrections. How would you design the usage-data processing flow?

B · Business understanding and domain modeling31
- Renewal fell by six percentage points this quarter, while the share of small customers among new accounts rose. How would you segment customers, usage periods, and service cost to determine whether product value fell or the customer mix changed?
- Sales reports growth using signed contract value, but customers will not use the product for months. How would you distinguish contracting, fulfillment, revenue recognition, and customer value, and explain what the team should observe?
- A premium service tier earns more revenue but consumes more human support, and renewal has not improved. How would you determine whether it creates incremental value?
- A product is sold once but requires long-term support and upgrades. Revenue is growing while the service queue accumulates. How would you decide whether these sales still create value?
- A customer buys a bundle and then asks to refund one item. How should the original bundle discount be reallocated?
- A customer cancels before service begins, but the contract, product page, and support system describe the cancellation fee differently. How would you determine the refund and make future orders follow a consistent rule?
- A major customer has a special rate in its contract, but the exception may end at renewal. How would systems and operations avoid keeping the old exception indefinitely?
- A partner prepays credits that expire, and a customer uses or refunds them in several batches around the expiry date. How would you represent credits, consumption, expiry, and refunds in settlement?
- In a system that handles money, how should accounting and billing be designed so the numbers are clear and reconcile? How do you model accounts, entries, holds, settlement, and reconciliation, and how do you trace and correct an error?
- How should amounts, currencies, rounding, and time zones be expressed in a transaction and settlement model? Which practices look fine but break at reconciliation?
- An order may use a membership discount, channel offer, and coupon, with exceptions by product, contract, or region. How would you define eligibility and calculation order so customers see a consistent amount and finance can reconcile refunds?
- The revenue share between a platform and its creators changes in tiers with monthly volume. How would you express this settlement rule so product, engineering, and finance can each verify it independently?
- Taking concepts such as orders, contracts, and settlements, how are they mapped into the data model? Which concepts were split into several entities, which were merged, and why?
- How does your own business model interact with the industry's or a partner's common model? When fields, definitions, or concepts do not line up, how do you handle it?
- Orders, payments, and refunds are often stored in one table. How would you distinguish their business identities, lifecycles, and cardinalities? Compare conditions, costs, and validation for separate models and combined storage.
- A company buys 100 seats used across subsidiaries. Headquarters signs the contract, but some subsidiaries want separate invoices and permission administrators. How would you distinguish customer, contract, organization, account, member, and seat so access and billing stay consistent?
- An account may hold a base plan, temporary trial, campaign benefit, and support credit. Systems implement precedence differently, so access sometimes flips. How would you define eligibility and conflict rules?
- A service changes eligibility from “current account status” to “account status at application time plus a risk-review result.” Support needs to explain historical denials, and audit must reproduce the original decision. How would you evolve rules and data models without conflating old and new outcomes?
- Enterprise contracts specify first response, service restoration, and final resolution times, each with different pause conditions. Support tracks one SLA timer, causing disputes. How would you model this?
- An enterprise product charges a monthly subscription, overage usage, and a minimum-spend true-up. How would you define billing periods, usage attribution, price effective time, and invoice explanations so a customer can reconcile the charges?
- A promotion increases sales volume, but new customers’ first orders remain unprofitable after discounts, channel fees, and fulfillment costs. How would you isolate the loss and decide whether to change the offer threshold, audience, channel, or stop the promotion?
- A user orders through a channel and later receives a refund, chargeback, or cancellation. How would you define order value, attribution window, and channel cost so marketing analysis and finance settlement can both explain the same outcome?
- A new plan makes more users willing to try the product, but some customers who would have bought a higher-priced plan switch to the cheaper option. What commercial model and observation window would you use to judge whether the plan portfolio creates incremental value?
- Map the value flow among users, suppliers, the platform, and payers in a two-sided marketplace you know. Explain how value and responsibility change when a service is not fulfilled.
- A new industry or regulatory requirement forces a product workflow change. How would you trace from the requirement to affected participants, value-chain steps, business commitments, and internal systems?
- The same person may encounter a product through ads, an agency, a partner, and a self-serve channel, and different parties may pay. How would you distinguish customer, buyer, user, and acquisition touchpoint in the business model?
- Partner settlement must connect external order IDs, internal orders, payments, and refunds, but systems use different keys and update times. How would you build the mappings and reconciliation process?
- Business units use an “active customer” metric, but some define it by payment, others by usage, and others by likelihood to renew. How would you decide which definitions should be standardized and which should remain distinct concepts?
- The commercial rule for a service changes from a free trial to a refund after conditions are met, while historical orders were signed under the old terms. How would you evolve the model and workflow so both old and new transactions remain explainable?
- The team plans to enter an adjacent market where users, payers, and fulfillment parties differ. How would you map the value chain and determine whose problem the product should solve first?
- Customers upgrade, downgrade, or pause subscriptions mid-cycle, while sales and finance disagree on revenue recognition. How would you express the rules and handle historical invoices?

C · Value judgment and direction setting14
- Visits and registrations are growing, but match success is falling. Demand concentrates in a few regions while suppliers are scattered. How would you find the liquidity bottleneck and choose where to invest first?
- A marketplace raises commission by two points. Revenue rises short term, but some high-quality suppliers list less often; buyer conversion has not moved yet. How would you assess long-term impact?
- After a subscription price increase, monthly revenue rises 8%, but cancellations grow among small core customers. Sales wants to continue. How would you estimate net benefit and long-term risk?
- Gross margin is steady, but standard-service revenue falls while custom-service revenue grows, along with implementation and support hours. How would you determine whether growth is healthy?
- Product, operations, and sales reports all say “retention,” but refer to return visits, key-feature use, and renewal. How would you clarify the measures so each name maps to a user behavior and business decision?
- A new automated workflow doubles processing speed and reduces human review, but errors have a greater impact on a small group of high-value customers. How would you assess net value and decide whether to expand it?
- A major customer will pay a high price for a custom feature, but reuse by other customers is uncertain. Ongoing maintenance, permissions, and data rules add cost, and sales has promised a delivery date. How would you compare a one-off build, productizing it, a service, or declining—and decide whether to invest?
- As the industry enters a stock era, the company demands a complete shift from thinking in transaction volume to thinking in net profit. How do you raise net profit by adjusting the take rate and optimizing supply-chain operating costs without triggering large-scale exits or protests from merchants or creators?
- A competitor launches a lower-priced substitute. Customers start negotiating harder, but usage has not changed much. How would you choose a response?
- A free feature attracts many active users, but inference and support costs rise too. How would you evaluate the business role of the free tier?
- Marketplace subsidies increase transactions, but supply and demand fall back when subsidies stop. How would you judge whether the subsidies created sustainable value?
- During a brand campaign, organic search and direct visits rise, while search-ad spend also increases. How would you estimate brand contribution without counting conversions intercepted by performance ads as brand outcomes?
- A campaign randomly holds out 10% of users, but they may still receive sales outreach and organic recommendations. Conversion is higher in treatment, and the channel team wants more budget. How would you assess contamination and results?
- Orders rise 30% during a discount campaign, but many come from existing customers who would have bought anyway, and product mix changes. How would you estimate incremental gross margin?
