Software Development Engineer Intern Interview

Anonymous Employee
Seattle, WA

I applied online and the process took 4+ weeks - interviewed at Amazon.com.

Interview Details – Applied online and got a email from recruiter after around 3 weeks. Scheduled a interview after 4 days.
There were 2 back to back phone interviews. Both the interviewers were very friendly. They initially asked questions on my background and asked to explain any of my project. Then they started asking technical questions along with algorithms/data structure. I had to explain the logic and after that I had to speak out the code explaining what I am doing. They always asked my to optimize the code to reduce time/space complexity. Overall I could answer all the questions they asked.

Interview Questions

  • Calculate the square root of a number.   View Answers (3)
  • A design question based on a real time customer scenario on Amazon website. Was asked to design the system as efficiently as possible. It included many structures inside other data structures which made the design very complex.   Answer Question

Software Development Engineer Intern Interview

Anonymous Employee
Telephone, TX

I applied through college or university and the process took 2 months - interviewed at Amazon.com in February 2012.

Interview Details – Three phone screens, two back to back, one a few weeks later. I think did poorly on my first interview (nervous), and very well on the second. The third was likely a tie-breaker. No behavioral questions were asked except basic "tell me about a recent project you worked on" chit chat. Questions emphasized data structures, algorithms, and object-oriented analysis.

Interview Question – How would you design a customer product review system and make it scalable (describe in terms of algorithms and data structures)?   Answer Question

Financial Analyst Intern Interview

Anonymous Employee
Seattle, WA

I applied through college or university - interviewed at Amazon.com in August 2012.

Interview Details – As others noted, 4 interviews back to back, one bar raiser. Two the interviewers had a mix of analytical questions and "case" type questions. Overall interesting and fun experience; the people doing the interviews for the most part were nice and helped you start in the right direction if you didn't know how to answer at first.

Interview Question – How should you determine whether or not to drop the price of a kindle accessory? (note that they had numbers and wanted a specific answer regarding these, not a general one).   Answer Question

Software Development Engineer Intern Interview

Anonymous Employee
Seattle, WA

I applied through an employee referral and the process took 2 months - interviewed at Amazon.com.

Interview Details – After submitting resume, received an email saying that I was selected for two 45-minute phone screens, and asked for my schedule so that they could plan something that would work for me. My screens were back to back the following week. Both interviews were incredibly nice. The first asked me some questions about myself and some projects that I had worked on, then asked me some basic OO questions. He then asked me one coding problem, which we worked through online.

The second interview was all coding, working through variations on a binary tree problem. The interviewer had an accent, but it wasn't too harsh, and he was very pleasant. Both let me drive the conversation, and I made sure to keep talking the whole time.

I thought I had done ok, but not super well. I aced the second interview, but stumbled through the first interviewer's coding question. About a week or two later, I received an email saying that I had gotten the internship.

Interview Question – Design an algorithm to take a list of strings as well as a single input string, and return the indices of the list which are anagrams of the input string, disregarding special characters.

Given a binary tree which is a sum tree, write an algorithm to determine whether the tree is a valid sum tree or not. Then, write an algorithm that will fix the tree to make it a sum tree. Then, write an algorithm which will fix a tree to make it a sum tree by only using addition.

Software Development Engineer Intern Interview

Anonymous Employee

I applied online and interviewed at Amazon.com.

Interview Details – Applied directly through their job postings and was contacted by email and then by phone to setup interviews.

Initially two phone interviews each 45 minutes in length back-to-back, with a 15 minute break in-between. Later that evening I was contacted to setup a third phone interview. When I completed the third phone screen I was informed that it was for the full time SDE position and not an internship (However I noticed no difference in type or difficulty of questions between it and the previous two phone interviews.)

Each interview consisted of a minor overview of what position my interviewer held in the company followed by some minor questions about my resume. (i.e. questions about the programming languages I was familiar with, questions about the difference between imperative and functional programming since I had experience with prolog, haskell, and scheme). Following those there were two or three warm up questions dealing with high level concepts in OOP and data structures. A few questions asking me how I would solve a given computing problem without actually producing code. A more difficult computing question where I was asked to produce code either on my side dictating it to my interviewer or through a shared editor. Finally a fairly difficult algorithms question about working in a very large problem space (working with large data sets) not producing code but attempting to find the most efficient solution.

Interview Question – Given an integer N and an array of unsorted integers A find all pairs of numbers within A which add up to N. (This is the only question I can remember and I had trouble thinking of an answer at the time)   View Answers (3)

Negotiation Details – As it was an internship the offer was basically take it or leave it. That being said the offer was more generous than one would feel inclined to haggle over anyways.

Software Development Engineer Intern Interview

Anonymous Employee

I applied online and the process took 3 months - interviewed at Amazon.com.

Interview Details – Filled out an application online, and they got back to be in a few weeks. Asked for a phone screening. 2 in a row one after another, about 45 minutes each. About a month later, when I wasn't expected to hear from amazon again, they emailed me again asking to set up another phone interview. After reading reviews here, I was expecting that the next step would be for them to fly me to Seattle, however the interns don't get an in-person interview at all. Got an offer about a month after the lase screening

Interview Question – Q's involved string manipulations, OO design, algorithms and data structures.   View Answer

Negotiation Details – All interns of the same education level get the same pay.
