The first round was an online coding test consisting of 2 questions to be solved in 90 minutes. Question 1: Find the longest subarray with a given sum. Difficulty: Medium Approach: Used sliding window and prefix sums to optimize. Question 2: Simulate an elevator's operations based on floor requests. Difficulty: Hard Approach: Focused on edge cases like overlapping floor requests and efficient traversal. Technical Round 1: Duration: 1 Hour Questions: Problem-solving: Implement a function to merge overlapping intervals. Follow-up: Optimize for space and discuss edge cases. Brief discussion on past projects. Technical Round 2:
