  1. Imagine Slice's checkout flow. A user adds items to their cart, proceeds to checkout, selects a payment method (e.g., UPI, card), and then encounters an error just before the final confirmation. The error message is generic, 'Payment Failed.' Describe your debugging process to identify the root cause, considering potential issues in the frontend, backend, payment gateway integration, or even network latency. What specific logs or monitoring tools would you look for?

    Software EngineerDebugging and System AnalysisTests: Evaluates problem-solving skills, systematic debugging approach, and understanding of distributed system interactions in a critical user flow.

  2. Slice processes a massive volume of transactions daily. Design a distributed system for processing these payments. Consider aspects like high availability, fault tolerance, idempotency, and eventual consistency. How would you ensure that duplicate payments are not processed and that refunds are handled correctly, even if a payment service experiences an outage?

    Software EngineerSystem DesignTests: Assesses ability to design scalable, reliable, and fault-tolerant distributed systems for high-throughput financial transactions.

  3. Slice offers a unified checkout experience across various merchants. Write a SQL query to identify the top 5 merchants by the number of successful transactions completed through Slice in the last month, excluding any transactions that were initiated but not completed.

    Data ScientistSQL and Data AnalysisTests: Tests SQL proficiency and ability to extract specific business metrics from transactional data.

  4. Slice's core value proposition is providing credit to users who might not have traditional credit histories. How would you design an A/B test to evaluate the impact of offering a slightly higher credit limit to a segment of users who have consistently made timely payments on Slice? What are the key metrics you would track, and how would you define success?

    Data ScientistExperiment Design and MetricsTests: Evaluates understanding of A/B testing methodology, experimental design, and selection of appropriate metrics for evaluating product changes.

  5. Slice aims to be the primary payment and credit platform for online shoppers in India. What are the biggest product challenges Slice faces today in achieving this vision? How would you prioritize features for the next 12 months to address these challenges?

    Product ManagerProduct Strategy and PrioritizationTests: Assesses strategic thinking, understanding of market dynamics, and ability to prioritize product initiatives based on business goals.

  6. Consider Slice's 'Buy Now, Pay Later' (BNPL) feature. Imagine a scenario where a significant number of users are defaulting on their payments. What data would you look at to understand the root causes of this increase in defaults? How would you propose iterating on the product to mitigate this risk while still serving the target user base?

    Product ManagerProduct Analytics and IterationTests: Tests analytical skills to diagnose product issues and the ability to propose data-driven product solutions for complex problems.
