Interview questions [1]
Question 1
Given three arrays. Find all the pairs from the two arrays such that the sum of those elements is in the third array.
Reverse a Linked List
Find Kth Max occurring element in the Array.
Used HashMap and Heap to solve the question.
Time O(n*logn)
Find K-th Permutation Sequence: Given N and K, where N is the sequence of numbers from 1 to N([1,2,3….. N]) find the Kth permutation sequence.
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. After the OA, shortlisted candidates typically proceed to one or more technical interview rounds covering coding, system design, and behavioral questions based on Amazon's Leadership Principles.
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.

Question 1
Number of Islands (LC 200 - Medium): You are heavily advised to know how to traverse connected components using a 2D grid.
Interview involved one screening OA and one final day, 3 back to back interviews, one technical, one behavioral and one mix. Focused on leader ship principles and DSA and algo
