I was given 2 coding problems to solve and asked to write the approach for it.

Coding Challenge questions:
1. To find maximum presentations possible by diff companies, given arrival and duration of stay of each company to present. (Similar to meeting rooms problem on Leetcode)
2. Given an array of parking lot numbers, where cars are parked, find the minimum length of the roof to cover k cars.
I received an Online Assessment (OA) invitation from Amazon. The assessment consisted of two coding questions of medium to hard difficulty, focusing on data structures, algorithms, and problem-solving skills. The questions required efficient solutions with optimized time and space complexity.

Applied online via career site, received OA link within 2 days and cleared it, Round 1- DSA, Round-2 DSA, Round 3- System Design, Round 4- Mixed Technical Discussion and Behavioral.
