# AmazeWoW Interview Experience

• Last Updated : 11 Nov, 2020

AmazeWoW is a development initiative with internship and FTE SDE (Full-time Software Development Engineer) opportunities for Amazon in India, focused on bringing in top talent from engineering institutes. I got to know about the program through my campus placement cell. I applied for the role at the AmazeWiT portal and passed the resume screening.

In about two weeks, I got the confirmation for being shortlisted for online assessment for the 6 months Internship + FTE role.

Round 1(Online Assessment): This online assessment comprised of 30 questions with 2 coding questions and 28 MCQs.

Coding Questions:

1. It was one of the most common Dynamic Programming problems: Longest decreasing sub-sequence.
2. It was an easy question that needed us to find out the mean, median, and mode in an array.

The MCQs were difficult that required a good understanding of Computer fundamentals. I was shortlisted for the Technical Interview Round 1. Amazon organized various webinars to guide candidates for the interviews.

Round 2 (Virtual Technical Interview 1): This was round 1 of the Technical Interview series. The interviewer didn’t seem to be interested in knowing about me or anything else, so he immediately started with the coding part. It was a 45 minutes interview with 2 coding questions:

1. There is a stream of numbers scattered in memory, and we need to find out the frequency of corrupted data. Corrupted data resembles a given pattern. (Not sure if this was the exact question. It was a bit confusing.)
2. This problem was a variation of one of the most famous Graphs problems, the Number of Islands. We’re given a 2D matrix of 0’s and 1’s, where 1 represents land, and 0 represents water. All the 1’s together represent an island. So, we need to find out:
• The number of islands
• The size of the largest island
• Number of islands nearest to a given coordinate

I could attempt both the problems but wasn’t able to satisfy the interviewer with my approach. I couldn’t move ahead for further rounds.

Mistakes:

1. Didn’t understand the question completely: I couldn’t understand the first question correctly. So, I tried every possible approach I could think of at the moment and most of them were not relevant to the question asked.
2. Didn’t perform self testing of the code: For the second question, I completed the first two parts correctly but for the third part, I neither reviewed my code nor performed the testing.
