This candidate applied for an SDE-2 role at Nykaa via LinkedIn, with 2.5 years of experience. The preparation involved practicing algorithms from GeeksforGeeks, data structures from GeeksforGeeks and Leetcode, system design from Work@tech and YouTube, OOPS, and database theory.

Round 1 (Coding - Video Call - 60 Mins): This was a coding round focused on DSA, with two medium-level questions. One specific question mentioned was "Given N pairs of parentheses, write a function to generate and print all combinations of well-formed parentheses." The candidate spent 5-10 minutes building logic, tested with 5-6 test cases, explained the solution, and performed a dry run, satisfying the interviewer.

Round 2 (System Design - DB Design + LLD): The result of Round 1 was received within 30 minutes, and Round 2 was scheduled. This round was a system design round, specifically focusing on database design and Low-Level Design. The task was to "Design a Parking Lot", including its database design and writing LLD code for it.

Round 3 (Hiring Manager Round): This round involved many technical questions alongside LLD questions. A system design problem like "Design BookMyShow" was also mentioned as a potential topic. The candidate was advised to have a healthy interaction and good explanation of thoughts rather than just complete code.
