I applied through a recruiter. I interviewed at Amazon (São Paulo, São Paulo) in Mar 2017
Interview
I was first contacted by a Cape Town recruiter via e-mail. We schedule a first Skype session a couple of days later so the recruiter could explain the opportunity and learn more about my background and willingness to relocate.
1.5 weeks later, two engineers called me and gave me 2 or 3 programming tests that I should answer by writing code in a web "whiteboard".
On the same day I got another e-mail from the recruiter congratulating me and asking me to prepare for the on site interviews 2 weeks later.
For the on site interview they flew me to São Paulo. This phase is composed of 5 interviews of 45-50 minites duration within a single morning. 3 of the interviews are technical (1 about architecture, 1 about programming and OO design and the last is more heavy in algorithms and data structures), 2 are competency based (how would you handle a given situation, give examples from your experience etc).
Overall It was a fair and pleasant process. Most of the engineers were even nicer than they needed to be in this type of interview. The questions are hard but there are zero tricky questions. Considering that they will be paying the costs to relocate the professional to another continent and all, I think the hiring process is fair for the company and for the candidate. After all, who would like to be relocated to another country just to find out the interview did not test or prepare you to handle the job?

Question 1
Given a matrix of pixels painted black or white (true or false in this array), and given a x and y position, paint all white pixels black and stop when a black boundary is found (sort of like the bucket paint tool in Paintbrush).
I applied through an employee referral. I interviewed at Amazon
Interview
The process started with a brief 30-minute phone screening with a recruiter, focusing on my background and resume.
After that, I was invite to a technical video interview with a senior engineer. This round lasted about 60 minutes, starting with a brief introduction, followed by a live coding challenge on a shared editor, and ended with a few questions about system design basics and my past projects.

Question 1
Implement a function to find the first non-repeating character in a string and discuss its time and space complexity.
I got a take home exam on HackerRank that I did not do great in. I did not perfectly solve every problem. Then it was another problem with "AI assistance" except the AI seemed programmed to be as useless as possible, it's genuinely better to just not use it. Somehow I got the next interview anyways, who also asked me some leetcode style questions and asked my to explain my experience and then next day they rejected me.

Question 1
What is the most complex problem I have encountered?
The interview process was straightforward with no surprises — three coding rounds (LeetCode medium difficulty), a system design round, and a cultural fit conversation. The interviewers were pleasant and the overall atmosphere was positive.
That said, it's worth noting that this format feels dated. Even before the rise of AI, LeetCode-style assessments were a questionable proxy for real-world engineering ability and cultural fit. In today's environment, where AI can solve most of these problems instantly, continuing to use this framework raises the question of what signal it's actually measuring.

Question 1
For coding it was ask very similar to number of islands (2D grid search) with a twist.
