Amazon.com Testing Engineer Interview Questions & Reviews

Interview Details – 2 interviews

Interview Details – Drop my resume to amazon career website. A month later, one recruiter asked me go directly onsite without phone interview. Onsite consist of a group project start from 10am to 5 pm and 1 round one on one interview. The interview is about how you design the project and how to validate your test case.

Reason for Declining – I'm not very interesting in testing.

Interview Details – Phone screen was technical and involved writing code on a collaborative website.
Onsite interview was five 1 hour interviews plus a lunch.
The interviews were very technical and a lot of time was spent coding on a white board.
None of the interviewers talk to each other between the interviewers so some of the questions were similar.
Phone screen question was how to find the second largest sum of any two pairs in an array of numbers
Onsite questions focused on writing an optimized loop to iterate over data looking for some common characteristic. Or the data was iterating through links, and determining when all link paths had been exhausted.

Dress was casual for the interview

Negotiation Details – I named my asking amount, and they gave it to me plus a signing bonus. The position I accepted was different than the one I interviewed for.

Interview Details – Applied the job through referral. Recruiter contacted me within a few days and scheduled phone screens very promptly. The first phone screen was with the hiring manager. He asked open ended technical questions for discussion and a coding question. Second phone screen was with a technical lead and the questions were more data structure oriented.

Interview Details – I applied online. Heard back in a month in early January, and had two 45-min back-to-back phone interviews in late January. The interviews are technical. But the first interviewer had a strong accent that I couldn't understand some problems and had to ask him to say them again.

The first interview asked about my experience with Amazon.com, what I don't like and what I like. Then there were a couple of data structures problems on array, string and etc., regarding time complexity. Then he asked me to program online given a string, convert it to a number. Then test cases of the same problem.

The second interview was about graph. Given two nodes in a large relationship graph like Facebook, find the shortest path from one to another.

Interview Details – on campus interview. straightforward

Negotiation Details – no

Interview Details – A friend linked me up with an Amazon recruiter. They flew me out and covered all my expenses. The interview process was very technical and data structure oriented. My advice is if you don't truly love programming, look elsewhere. It seemed very fast paced, and that everybody worked extraordinarily hard.

Interview Details – I was scheduled for two back-to-back 45 minute long phone interviews. Both of the interviewers were quite pleasant, and they dove into technical problems immediately. Due to technical reasons (I really chose the wrong place to sit-- the call dropped several times and the internet stopped working), the first call was rescheduled for a week later. Both interviewers used an online collaborative coding website for the technical questions instead of asking me to write on paper. The technical questions were nothing too unexpected:
- Find the intersection of two arrays of integers (the elements that are in both)
- Given a set of integers, produce its power set (the set of all subsets of the original set)
- Reverse a linked list
- Given a string, what characters are in it?
Only one interviewer asked me about my resume ("tell me about a technical challenge on a project you've worked on").

Interview Details – Interview process:
1. 3 Phone interviews - Fully technical. Mostly they ask 3 questions in 45 minutes time. They give time for us to think and solve the problem. Mostly they tested problem solving ability.
