Amazon Internship Interview Experience | On-Campus 2021
- 7 easy debugging questions related to algorithms to be done in 20 minutes.
- 2 coding questions with varying difficulty of easy to medium to be solved in 70 minutes. I was given the following two problems:
- A question on arrays that can be solved greedily.
- A variation of https://www.geeksforgeeks.org/value-to-be-subtracted-from-array-elements-to-make-sum-of-all-elements-equals-k/
Other questions that were asked from my friends:
Become a success story instead of just reading about them. Prepare for coding interviews at Amazon and other top product-based companies with our Amazon Test Series. Includes topic-wise practice questions on all important DSA topics along with 10 practice contests of 2 hours each. Designed by industry experts that will surely help you practice and sharpen your programming skills. Wait no more, start your preparation today!
- An easy question using an implementation of Dijkstra’s Algorithm.
- Questions based on behavior and work style. It takes about 20 minutes.
- 24 reasoning questions to be solved in 35 minutes. They’re a bit easier as NTSE Stage II MAT questions.
Interview: There was only one round of interviews. The interview started without any formalities. I was given a live code link. The panel consisted of 2-3 individuals joining in and out, but only one of them was interacting with me. 2 easy questions were asked during the interview.
Question 1: An apparently tricky question that could be solved greedily.
Question 2: https://www.geeksforgeeks.org/find-number-of-islands/. The interviewer further asked if this could be done by using constant extra space.
The interviewer asked if I had any questions. I asked questions like how algorithms are used in the field they’re working in and what teams do what kind of tasks.
Finally, 7 people, including me, were selected out of 41 shortlisted students.
