Software Development Engineer Intern Interview

Anonymous Employee

I applied through a recruiter and the process took 3 weeks - interviewed at Amazon.com.

Interview Details Recruiter reached out at the end of November asking to schedule 2 back to back interviews which we set up for the next week. Exactly 2 weeks later (almost to the minute) the recruiter replied with an offer. We set up a phone call to discuss the details of the offer a week later and after that I accepted.

Interview Questions

  • Interview 1: Started with basic cv chit-chat and discussing projects. Was asked general information (complexity and high level implementation) about data structures you'd expect to find in standard libraries. Continued on to a super simple coding question that was something like reversing a string in place. Then had a longer coding question that was a variant on the subtree sum problem and could be made to run in O(n) time with some preprocessing. Overall not particularly difficult.   Answer Question
  • Interview 2: Like the first interview this one started with basic cv questions and a simple coding question. Then moved onto a longer question that was basically weighted graph search but the edge weights were dynamic. Harder than the first interview but still not too difficult compared to other companies. I'd say about similar in difficulty to google but easier than palantir.   Answer Question

Negotiation Details – I don't think internship offers are negotiable but in any case the offer was much higher than I'd expected.

Software Development Engineer Intern Interview

I applied through college or university and the process took 5 days - interviewed at Amazon.com.

Interview Details They attended a local career fair at my university - I handed them my resume and was asked to apply online with a certain code for SDE Interns. I applied and received a call scheduled for the next following day to interview. Interviewed, and got the email offer within 4 days.

Interview Question – Very typical codeable question for an undergrad - something you would get from cracking the coding interview. Only one question was asked - I then chatted with both interviewers for 45 minutes each separately for two back-to-back interviews.   Answer Question

Software Development Engineer Intern Interview

Anonymous Interview Candidate

I applied through an employee referral and the process took 2+ weeks - interviewed at Amazon.com in March 2014.

Interview Details Got the interview from AWS team. 2 back-to-back 45 mins interview.
First interviewer(an indian engineer with terrible accent) asked me a classical Top K question, gave him a solution literally in a minute. However the solution needs a max-heap, commonly just use its api but this time he asked me to implement all, got quite unexpected here, it took me almost 30 mins to finish it. At last I asked question about openstack, unexpectedly he didn't know a thing about it.
Second round was about string anagrams, still gave him a solution very fast(hash table, O(n) time and O(1) space), it is the best solution. After this talked about my current project, I guess this is where I blew the intern opportunity cause I said it is totally boring :-/ .
Two interviewers were not nice, sometimes felt quite unpleasant. The HR really didn't respond any of my question and email, and I was told no offer a week later.

Software Engineer Intern Interview

Anonymous Interview Candidate
Pittsburgh, PA (US)

I applied through college or university - interviewed at Amazon.com in March 2014.

Interview Details I applied during the Spring Employment Opportunities Conference of our university, and got the on-campus interview. It was 2 consecutive interviews, 45 minutes for each. 1-2 questions for each interview, depend on how fast you can finish the first problem. Write the code on white board.

non-technical questions:
how did you solve it when you have conflicts with teammates?
Tell about one of the open-ended projects that you have done.

Interview Question – given an integer, output all the prime factors of that integer, ex:
input: 6, output: 2,3
input 25, output: 5, 5

given an integer array, output all the numbers that appear odd number of times, ex:
input: 1,2,1,3,3,4
output: 2, 4
