Software Development Engineering Intern Interview

Anonymous Interview Candidate
Seattle, WA (US)

I applied through an employee referral and the process took 1 week - interviewed at Amazon.com in February 2012.

Interview Details A friend of mine submitted my resume to a hiring manager and I got a phone call about a week later to set up a phone interview. The phone interview involved two different people, both of whom went straight into the technical questioning. There was none of the typical interview banter or "what's your greatest weakness" sort of vagueness. The second guy didn't even have inflection in his voice. He was just a cold, hard, questioning robot... creepy!

About halfway through the phone call I was asked to sit down at my computer and log on to a website where the interviewer watched me write some code to solve a problem he'd specified (printing a series of numbers to a console in a spiral pattern). It was a bit difficult since every time I stopped to think he'd ask me what I was thinking. After several minutes of thinking out loud and typing nervously I managed to complete the problem.

After the online portion of the interview, I was given homework (see "Most Difficult or Unexpected Question"), and told to submit it to them by the end of the day! I had a hot date with tickets to a show that evening, but as the hours went by it became clear that I was going to have to cancel to work on the interview problem. Frustrated and bitter, I resigned to submit what I had by midnight along with documentation on the missing aspects of my solution.

A few days went by and I heard nothing. I still had some questions about the internship that I didn't have a chance to ask over the phone, so I e-mailed my recruiter. She replied the next day with a form letter telling me that they'd decided to pursue other candidates.

Interview Question – Recreate the StringBuilder class in C++ from the ground up.   Answer Question

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

Interview Details Got an email saying they liked my resume and I scheduled for an interview on campus (this was at UCSD). The interview consisted of 2 45 minute interviews. They were very nice people and very helpful when I was stuck on some code. Interesting interview. Heard back the day after and did not get the offer.

Software Engineer Intern Interview

Anonymous Interview Candidate

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

Interview Details I applied for the software engineering internship. I had back to back interviews, and then a final interview a couple weeks later.

The interviews were technical interviews, and they were very challenging. I could not figure out some of the question.

Interview Question – There were some questions based on graph theory that were very simply stated, but required a very well-thought-out precise solution.   Answer Question

Supply Chain Intern Interview

Anonymous Interview Candidate

I applied through a recruiter and the process took 2+ weeks - interviewed at Amazon.com in October 2011.

Interview Details This interview process was definitely an interesting one. It was a very difficult interview when compared to what most Supply Chain companies ask. The first round was behavioral and tested my Supply Chain knowledge, while the second round was a lot of thinking problems. I was very impressed that Amazon called me 2-3 days after my second interview to let me know that I was not receiving an offer; it was much better than an email.

Financial Analyst Intern Interview

Anonymous Interview Candidate
Seattle, WA (US)

I applied through college or university and the process took a day - interviewed at Amazon.com in September 2011.

Interview Details This interview consists of 4 - 30 minute one-on-one interviews with 4 different people. They ask a few personal questions but a lot of financial usage questions. They did not present me with any financial statements as past commenters described. Instead, it was big hypotheticals like "if you invent a brand new product that has no comparisons, describe how you would determine a price and quantity to produce." Or, "what are 3 numbers the CFO probably wants to see on a daily basis?" It is very easy to stall out into awkward silence even if you know the material deep down.

Interview Questions

  • What are 3 numbers the CFO would look at on a daily basis?   Answer Question
  • How do you price a brand new product?   Answer Question
  • How do you decide whether to include a 5 dollar free download voucher with each sale of a cd box set?   Answer Question

Software Engineer Intern Interview

Anonymous Interview Candidate
Tempe, AZ (US)

I applied through college or university and the process took a day - interviewed at Amazon.com in March 2011.

Interview Details It consisted of 2 45 minutes back to back interviews. Both are skill questions.
The first interview consisted of a group of jobs in which some of them had dependencies, meaning that some had to be completed first before one could start. Think of this as a graph with pointing arrows. Create an algorithm that would spit out the most efficient/best job sequence. The result would be something along these lines: first job3, job4; second job1; third job5, job6, etc. What data structure would you use and how would you represent it? Explain it with pseudocode, then write it on code.
The second interview consisted of an expression tree. What structure would you use to represent this? Write code that would compute the result. Can you write it without using recursion? What's memory overhead?

Interview Questions

  • First Interview. What data structure to use, and how to solve the problem?   View Answer
  • Second Interview. Write code to compute result of expression binary tree? What's the time complexity?   View Answer

Software Development Engineer Intern Interview Interview

Anonymous Employee

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

Interview Details 2 hour back to back technical interview. You will get a third technical interview if they think you were on the fence.

Hashing, data structures, and design questions. They also asked me if i took the algorithms class, then they proceeded to ask me about NP-Complete problems etc. They were very nice overall. I recommend getting a good cell phone reception and internet access before the interview, because my call kept dropping on me during the interview. It dropped at least 6 times during my first technical interview, and I think they weren't happy about it, therefore I was sent to a third technical interview.

Software Developer Intern Interview

Anonymous Employee
College Park, MD (US)

I applied through an employee referral and the process took 1 week - interviewed at Amazon.com in February 2013.

Interview Details I had a friend hook me up with an interview from my university. I am a junior this year, and I don't believe that my resume would have gotten noticed otherwise. They came to my campus and conducted a 90 minute interview where two interviewers had me do 2 fairly difficult coding problems each (full out in my language of preference). I thought they weren't interested in me but heard back after one night that my interviewers were very impressed with me.

Interview Question – I had to implement a data structure for a last Least Recent Delete Cache and write relevant functions (it was a class for me since I used Java). Some functions included puts(Key key, Value value) and get(Key key). When I was stuck they helped me out.   Answer Question

Negotiation Details – haven't spoken with them yet about prices.

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
