This candidate interviewed for an SDE 2 position in Bangalore in October 2024, securing the opportunity via Naukri.

Round 1 (Virtual): This round involved discussions about the candidate's current and previous work experience, along with insights into their technical knowledge of Java, databases, and microservices. The focus was on assessing the candidate's fit based on technical and functional criteria.

Round 2 (DSA Round): Two Data Structures and Algorithms (DSA) questions were asked. The first question was "Group Anagrams". The second DSA question was not remembered by the candidate but was solved within the given time.

Round 3 (LLD Round): This Low-Level Design (LLD) round involved designing a coupon system for a simpler version of an Amazon-like e-commerce product. The initial requirement was to support a single coupon offering a 10% discount on the 11th order, usable once per user in a lifetime, and available again if the transaction failed. The system needed to integrate with existing Catalog/Product Service, Cart Service, and Order Service. The interviewer looked for critical thinking and design skills. The candidate noted that their solution, while refined, would require extensions for different coupon types or conditions.
