Recruiter Outreach The recruiter contacted me on Instahyre and sent an Online Assessment (OA) link.

Round 1 Online Assessment (OA) Consisted of 20 questions (Multiple Choice Questions + 2 LeetCode medium-level coding problems).

Round 2 Technical Interview 1 Questions asked: Zigzag traversal of a matrix. Detect a loop in a linked list. Find the intersection node of two linked lists. Many questions related to Spring Boot and Java.

Round 3 Technical Interview 2 The interviewer started with a brief introduction and shared their background at Razorpay. Questions asked: Find the non-duplicate number in an array (modifying the input array is allowed). Find a number that appears twice in a sorted array (using binary search). Find a number that appears twice in an unsorted array (using XOR logic). Discussed various project-related topics along with Java, Kafka, and Spring Boot. Managed to answer almost all questions, except a few related to Kafka.

Round 4 Hiring Manager Interview After contacting the recruiter, I joined the call. The HM asked me to solve a LeetCode problem involving finding the maximum sum subset in an array. Clarified whether it was about finding the maximum sum of a subarray or a subset. Explained a brute force approach along with its time and space complexity. Presented Kadane's algorithm for positive numbers and fixed the solution for negative numbers upon feedback. Faced some situational questions. Thought the round went well but later found out I was

rejected due to feedback indicating that I couldn't consider all possible scenarios for the problem. Conclusion: Except for the Hiring Manager round, all interviewers were nice and helpful. Despite the unfortunate outcome, it was a valuable experience.
