Round 1

Resume Shortlist

Interview Experience
They shortlisted about 30 people from around 700 applications on the basis of CGPA, Internships, Projects. PORs and Extra Curricular Activities weren't much important to them.
Interview Tips
Keep a safe CGPA above 8.
Round 2

Technical Interview

Interview Experience
Mostly they grilled me on my Projects and internships. A strategy based warehouse case study was to be solved. Since I was from Industrial Engineering background they asked me on a scheduling problem. And lastly a few puzzles and they kept on increasing the intensity at each question. Later on, he asked me why not go for a MS or PhD and a situation where you have put mind over matter.
Interview Tips
Most of the interviewers were very cool and friendly. DO NOT PANIC.
Round 3

Behavioural Interview

Interview Experience
They were simple life oriented questions. He asked me about my previous projects and BTP. Tell me about a situation you failed and why? Tell me a situation where you leaded a project? What experience do you have in industry? Why an e-commerce?
Interview Tips
Confidence is the key.
Round 4

HR Interview

Interview Experience
Regular HR questions. Again a puzzle. Tell me about a situation where the project was going downhill but you took that to another level from that. They told me about the working hours and asked me for a location preference.
Interview Tips
Show your zeal. Dont fumble.

Test Sections
  • Section 1: ONLINE TEST
Interview Experience
The selection procedure consisted of one online round followed by 4 face to face interviews.
1st round consisted of 20 MCQs of C/C++ and general aptitude. They shortlisted only 11 B.Techs after first round. Then we had 4 separate interviews out of which one was Bar Raiser round (which is most important).
Round 2

Technical Interview

Interview Experience
Each interview was of around an hour. They mainly emphasized on data structure part. I got a lot of questions from tree and linked list and few were based on Operating System's concepts. For most of the questions, they asked me to come up with more than one approach and also they introduced many variations in between. After the discussion of approach, I was supposed to write the complete code on paper.Each round was kind of elimination round and the Bar Raiser round was most important of all.
Resources

Preparation materials

Books
  • Data Structures and Algorithms made Easy by Narsimha Karumanchi,
General Tips
For improving coding skills, first code basic searching, sorting and graph algorithms.Then try to program few random questions of trees and linked list while studying there concepts. Then practice some questions from sites like codechef or codeforces and also try to participate in the competitions that take place on these sites.For Operating Systems, just go through the book written by "S Galvin" and try to clear concepts of memory management part.

Apart from these main topics, just have a glance at these few topics:

Database : Basic Queries, Indexing, Transaction

OOP : Definition with understanding of four features of OOPs.Among non-technical stuffs, practice some famous puzzles (just Google it).

After all these done, just keep on solving interviews questions being updated regularly at geeksforgeeks

Overall Experience was very good and challenging as it was the very first day of placement and our interviews went till 4 in the morning. So when the result came, we were very excited.

    General Tips
    DOs :



    1. Amazon always looks for leaders, so always be bold and don’t be afraid in front of the panel.
