Recruiter Call (30 mins):

General discussion about background, past projects, and expectations from the role. The recruiter also explained the process and timeline.

Technical Phone Screen (45 mins):

Conducted over Google Meet with a shared coding pad. The interviewer asked a medium-level data structures/algorithms problem and focused on how I explained my approach rather than just the final code.

Onsite / Virtual Interviews (3 rounds, ~45 mins each):

• Round 1: Coding + problem-solving (arrays/strings).
• Round 2: Data structures + algorithms (hash maps, trees).
• Round 3: Behavioral + system design-lite (scenarios about working in a team, plus designing a simple service like a URL shortener).

Given an array of integers, return the length of the longest subarray where the sum is equal to zero. Optimize your solution for both time and space complexity.
