Software Engineer Intern Interview

Anonymous Interview Candidate
Bucharest (Romania)

I applied online and the process took 2 weeks - interviewed at Amazon.com in December 2013.

Interview Details The interview consisted in an online test on coding platform, there were 2 problems to solve in 90 minutes, if memory serves.
The problems were easy and finished well before the time expired. However the platform which did provided feedback for the "Demo problem" did not provided any feedback whatsoever on the problems that I had to solve, probably because it was Amazons intentions.
Not so peachy.

Bangalore (India)

I applied through college or university and the process took a day - interviewed at Amazon.com in September 2013.

Interview Details It was a on-campus PI. There were 3 rounds. One coding round and 2 PI's.

Interview Question – There was as such no hard question for me. But unfortunately i was not prepared for this interview. Frankly this was my first ever interview. So yes i was bit nervous and i didn't knew about the tips and tricks for cracking the interview at that time. I was asked the following 2 questions:

1. given a tree, do the level order traversal of the tree. Explain the logic and write it's proper code not pseudo-code.

2 given a link list, Reverse a Linked List in groups of given size. write it's code.

Software Development Engineer Intern Interview

Anonymous Interview Candidate

I applied online - interviewed at Amazon.com in February 2014.

Interview Details I applied online from their career website. Got a reply after 3 to 4 weeks. There were 2 back to back 45 minutes interviews with a 15 mins break in between. Both were technical and focused on Data Structures.
In the first interview the interviewer asked me about my projects, why I got into this field and why I applied for this position and then asked the main programming question. The second interview was also more or less the same.

Interview Question – 1. Implement a hashset from scratch, write code for various methods of hashset.
2. Find all the pairs of numbers from a list that sums to a particular number.

Software Development Engineer In Test Intern Interview

Anonymous Employee

I applied through college or university and the process took a day - interviewed at Amazon.com.

Interview Details Emailed the recruiter my resume personally and got an email two weeks later saying that I have to set up two one hour phone interviews in the following week. Phone interviews were pretty much all technical with very little behavioral.

Phone interviews started off simple, "Let me tell you a little bit about myself", then "tell me a little bit about yourself." My first interviewer went straight from that to coding. You'll use an online program so he sees what you're typing. Other interviewer went through a bunch of short questions that were challenging, then to the coding.

After the two interviews, I got an offer a week later. All in all a simple hiring/interview process.

Interview Question – How do you create a routing table?   Answer Question

Interview Details Two phone calls covering the following:
Phone call 1-
a. Write a function to remove the nth last element from a singly linked list
b. Edge cases
c. Tests for that function
d. Input and output validation using status codes
e. API design considerations and error handling for the function

Phone call 2-
a. Functions to reverse a linked list recursively and then iteratively
b. Determine if two strings are anagrams, various approaches, space and time complexity
c. Given two singly linked list heads, determine if they are merged

e. Test the merge/intersect function, consider edge cases
f. Space and time complexity for all algorithms and data structures questions

Interview Question – Most unexpected- Recruiter was difficult to reach and had about <12hrs warning before scheduling interview. The actual interviews went well- the engineers were easy to talk to and walked through the problem solving.   Answer Question
