The process took 2 weeks. I interviewed at Amazon in Jul 2009
Interview
Got a call from the HR about a week after I posted my resume scheduling phone interview.
The phone interview went well with questions on data structures and coding.
how would you find a duplicate in an array of size n with numbers from 1 through n-1.
the time complexity, the next was on grep, and then one more question on data structures.
And time complexities.
Interview questions [1]
Question 1
given an array of records of size n, n is in the order of billions,
each record stores the co-ordinates (x,y,z)
find the m-closest records to the origin.
It started with an OA, and then after a few weeks, I got invited to four rounds of interviews: technical and behavioral at 3 of the 4, and behavioral only at one.
I applied online. I interviewed at Amazon (Calgary, AB) in Jun 2026
Interview
Online Assessment is the first step in the process. I didn’t have an HR phone screening and went straight to the OA after applying. It was sent to me about a week after I submitted my application.
Interview questions [1]
Question 1
The first question is LeetCode style algorithms question, and the second question gives a full stack repo (choice of Java, NodeJS, or Django) and asks to solve a backend issue which is causing a bug in the frontend. Unit tests must pass to pass the second question. You can run both backend/frontend indivdually or together
