The whole interview process consisted of online assessment, phone interview and onsite interview (4 interviews the same day). Each interview (except for online assessment) was divided into 2 parts - coding part and questions regarding existing career part.
I applied online. The process took 4 weeks. I interviewed at Amazon (Madrid) in Oct 2021
Interview
A long process, approximately a month and a half, with three types of interviews: coding assesment, by telephone and on-site (which was also done online due to the COVID situation).
The interviewers were very friendly, helpful at all times and made the conversation quite pleasant.
It is highly recommended to use leetcode to practice exercises and review the most common data structures and algorithms. The book Cracking the Coding Interview is very useful for the interview.
Interview questions [1]
Question 1
Coding assesment: two exercises similar to those in leetcode and a question for each one about complexity.
Phone Interview: questions on Amazon's leadership principles ("name a time when you had a deadline coming up and had to ask for more time") and a mid-level programming exercise.
On-site Interview: three interviews with different Amazon developers, about 45 minutes each. In all three, questions on Amazon's leadership principles and a programming exercise (OOP, data structures and a difficult exercise, which they don't expect you to come up with the solution, but to discuss how you could solve it).
