I applied online. The process took 5 months. I interviewed at Amazon
Interview
I only got an online assessment so far. I got it all correct, but I am still waiting on a response from them. The assessment consisted of two leetcode medium questions; the first one was a bit easier than the second one. Then had to answer questions based on situations as a sde at amazon choosing the best answers.
Interview questions [1]
Question 1
Developers at Amazon are working on a new algorithm to sort a permutation of n integers using the bitwise AND operation. For an array of integers, arr and some chosen integer k, you can swap the i-th element with the j-th element only if (arri] & arr[j)) = k, where '&' represents the bitwise AND operation.
Given an array arr of n integers which is a permutation of integers from 0 to n - 1, i.e. contains all integers from 0 to n - 1, find the value of the maximum non-negative integer k for which the array can be sorted using this algorithm. It can be shown that it is always possible to sort the array. Report O if the array is already sorted.
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.
