I applied through college or university. The process took 1 day. I interviewed at Amazon (Allahabad) in Jul 2014
Interview
It was an on-campus recruitment process. There were two sections in first round which was conducted online. First section had 20 mcq questions from c, c++, os and dbms, toc, dicrete maths etc.
After this round 21 students were selected and i was one of them.
First round was technical interview round. interviewer called me and he started asking questions to me. The first questions was- You are given a string without spaces and a dictionary which validate whether a word is valid or not. You have to convert the string into a sentence with spaces with all words valid in it. eg. ireadnewspaperdaily, now you have to convert it to i read newspaper daily.
i told him the idea by taking the letters of string one by one as a string and checking whether the word is valid or not. then he asked me to write the code.
2nd question- you are given a array of string with repeatition of strings. you have to print the non- repeating strings. I Describe him the idea of finding the non repeating string in O(n^2) compllexity. then he asked me to optimise it further.
after some time the results of first round was declared and i was not selected for 2nd round.
after this round 8 students were selected out of them 5 was hired for intern.
Interview questions [1]
Question 1
modified version of word break problem with printing the string.
Recruiter screen, followed by an online coding assessment and then a technical phone interview. The final round was a virtual onsite loop with multiple interviews covering data structures, system design, debugging, and Amazon Leadership Principles. The technical questions were practical but time-constrained, and the behavioural questions required specific examples using the STAR format.

Question 1
Design a scalable URL shortening service and explain how you would handle high read traffic, collisions, database schema, expiration, and basic monitoring.
That moment when the interviewer asked about finding indices in an array for a target sum was wild — I had just tackled something identical while prepping on PracHub. The interview included a technical round with another question about designing an in-memory LRU cache and a behavioral question about meeting tight deadlines. After a smooth discussion, I was told I'd received an offer, which I happily accepted. Overall, the process felt pretty straightforward and not overly challenging.
Interview questions [3]
Question 1
Given an array of integers return the indices of two numbers summing to a target
First round with hr screening - 2 leetcode questions then hr manager screening then the loop which consists of 4 interviews each an hour long. The 4 interview questions they asked where three medium leetcode questions. And one system design interview question about how to shadow deploy a test software to millions of users.
