Software Development Engineer Intern Interview

Anonymous Interview Candidate
London, England

I applied online and the process took 1 week - interviewed at Amazon.com in March 2014.

Interview Details I applied on their website in November. Had no response until February, when a recruiter contacted me, sending me a link to a Codility test (which was quite difficult). A week after I submitted the test, the recruiter called me to let me know that I passed the test and that they are inviting me to an onsite interview. The interview was difficult, but straightforward. The interviewer was very nice, and gave me hints when I felt that I was stuck.

Interview Question – The technical problem wasn't something very difficult at first sight, but the trick was finding out the most efficient solution, which involved using tries. This solution was not implementable in 45 minutes, so the interviewer asked me to implement a specific part from the solution. There were very few behavioural questions, and nothing unexpected.   Answer Question

Interview Details After completing a written exercise, I was invited for a telephone interview. The interview wasn't too difficult. There were few questions about my degree and my experience with teamwork.

Interview Question – Tell me when you improved a product, despite you were receiving a positive feedback from customers.   Answer Question

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 Developer Intern Interview

Anonymous Interview Candidate
London, England

I applied online and the process took a day - interviewed at Amazon.com in November 2013.

Interview Details Was sent a coding test with a question whereafter I was invited to come down to the London Development center for a on-site interview. The interview started directly with a whiteboard coding question involving a game (whose name I've forgotten sorry), after that there was a bit time for standard competency questions. It took one hour in total. Afterwards we were given a tour of the office. There was two interviewers who both had their nose down their laptop for the majority of the interview typing away notes (i presume) which was a bit of a distraction.

Interview Question – Writing code on a whiteboard is a bit of a challenge.   Answer Question

Software Intern Interview

Anonymous Interview Candidate
London, England

I interviewed at Amazon.com in March 2013.

Interview Details Applied for an internship at the Amazon Development Centre in London. Was sent an interesting technical test which I could complete in my own time - this was fairly simple but required some thought and I guess was also designed to test coding style etc.

After sending the code via email, they gave me an onsite interview in which we discussed the company briefly and then went straight into a whiteboarding problem involving the game Go, with a free choice of programming language (I chose Java).

I was quite nervous and this was my first experience of writing code on a whiteboard. I think they could see that I was not particularly confident in my solution (which I believe did work in the end), and that I took too long to progress.

Interview Question – Nothing particularly unexpected, the problem was around the right level, just lacked experience and confidence   Answer Question

Software Developer Intern Interview

Anonymous Interview Candidate
London, England

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

Interview Details I applied on internet.
A few days after, they sent me a program to write.
The program was not very difficult. But what they wanted was a program which could be very fast with a huge amounts of data.
The program:
I had a file representing a binary tree. In the file, it was coded like that:
B,C
NULL,B
C,A
...
Null meant that B was the main uppest node.
Then, C was the son of B and A the son of C.
The program took a depth and the file in input and should give the node which were at this depth in alphabetical order.

After that, I received a notification to go in London.
I was in front of two ingeneers of Amazon and it was technical questions.
The question was not difficult but I misunderstood the question bacause of my english and so I lost a lot of time.

Interview Question – The question was to fin the number of time an array was schifted.
For example:
[1 2 3 4 5 ] is 0 because it is in order
[7 5 6] is 1 because it should be [5 6 7]
[7 8 9 2] is 1 too.

I applied through college or university and the process took 2 weeks - interviewed at Amazon.com.

Interview Details Applied on college job site. Received an email to pick a date to have two 45 minute interviews at my college career center. First interview had a pretty common question. Second interview was more difficult, not types of question you would see in Cracking the Coding Interview. Overall, the interview was fair. Just practice writing out code on paper or a whiteboard if you have a face-to-face interview and brush up on basic algorithms! I interviewed on Thursday and received an email with offer on Monday.

Interview Question – Signed NDA   Answer Question

Negotiation Details – No negotiation for interns

Software Development Engineer Intern Interview

Anonymous Employee
Madison, WI (US)

I applied through college or university and the process took 1 week - interviewed at Amazon.com in February 2014.

Interview Details Applied online in January and after 2 month when Amazon hosted a career fair on our campus, got selected for back to back 90 mins interview. 45 mins with each interviewer. Questions are standard questions. If you do problems on UVA online judge, Topcoder or Hackerrank regularly, these type of interview questions should be fairly straightforward to answer.

Also, as many other big tech companies, just solving the problem is not enough. It's also important that you make sure your thought can be understood by others. Explaining how you come up with a solution with clarity is much more important that just solving all of the problems without saying how you did it.

There are four questions. 1 focus on math, 1 on building trees, 1 on linkedlist and 1 on string manipulation
As always, make sure you also understand the complexity and performance of you solution.

Negotiation Details – No negotiation. But I think the final offer (final salary) also depends on your performance during the interview.
