I have around 2 years of experience. I was approached by the recruiter on Instahyre and I was getting interviewed for AWS as an SDE-1. There were three technical interviews in total followed by a Managerial Round.
Phone Screening Round: This round was 1 hr long. The questions were :
- https://www.geeksforgeeks.org/next-greater-element/amp/
- https://www.geeksforgeeks.org/search-a-word-in-a-2d-grid-of-characters/amp/
Technical Interview 1: The questions were:
- https://leetcode.com/problems/lru-cache/
Check whether a given rotated array can be changed to the o actual array by reversing any of its subarrays. Eg: rotated array : [1,4,3,2,5] actual array: [1,2,3,4,5], so (4,3,2) subarray can be reversed in rotated array to obtain the actual array. Hence, the result: true
Technical Interview 2: This interview was focused on an algorithm design problem.
- There are n keys and n locks of different sizes. We cannot directly distinguish between the keys and locks by just looking at them, hence we cannot compare them with each other. A compare function takes in a key and lock as parameters and returns any of these three values:
{k1, k2, k3, k4,....}
{l1, l2, l3, l4, ......}
key fits the lock
1: the y is larger for the lock
-1: the key is smaller for the lockWrite a program to map all the given keys and locks with each other and print such pairs.
Managerial Round: This round was taken by the Hiring Manager. This round focuses on Amazon’s Leadership principles. Make sure you brush up on the principles pretty well before appearing for this round. A few of the questions were :
- Why do you want to work at Amazon?
- Have you faced ant situation where you worked under a tight deadline? How do you manage?
- What are your daily activities in your team?
- Any example where you did some innovation or coded anything to make the process simpler
- What are your contributions to your current team?
After each of the technical rounds also, the interviewers tend you access you on the Amazon Leadership principles. Hope this helps 🙂
