I applied through university. The process took 2 days. I interviewed at Amazon in Sept 2013
Interview
The written round was relatively easy. It contained 20 multiple choice questions on basic c, algorithms and probability. Some questions from OS and networking were there too but were easy. Coding questions were:
1. Left Rotate alternate k node in a link list.
2. Rotate the given matrix by 90 degrees i.e. the first row becomes the last column and second row becomes the second last column and so on.
Interview round 1:
Two questions were asked. One puzzle and the other coding question.
1. Given a Binary tree, how will you print it level wise. write efficient code.(further some modification in questions)
2. Find intersection of two link-list.
3.segregate even and odd in a link list.
Interview round 2:
1. Given a string, find all permutation and write code to remove duplicate ( use hashing).
2. Given 2d matrix of 0's and 1's in sorted fashion find column with maximum number of 1's.
Finally I got internship offer from them
Interview questions [1]
Question 1
Given a string, find all permutation and write code to remove duplicate ( use hashing).Time complexity and design of hash map.
It was fine but nothing special. Typical questions for an intern applying for an internship program. You wouldn't be surprised. Come with good questions. That always helps. Worst case scenario you don't get it.
Very good and it was easy to understand and the interview was very good and all answers are expected in star method its a method to answer to your questions
I attended the first round of online interview. It went okay. But I did have to reschedule the interview as the interviewer didn’t show up without any prior notice for the first time….
