I applied through university. The process took 3 weeks. I interviewed at Amazon in Mar 2011
Interview
I submitted my resume to an Amazon recruiter during a career fair and I was contacted for an interview a couple days later. The HR person who's in touch with me always takes about a week or two before responding to any of my emails, so scheduling the interview itself was a pain. She asked me when I'd be available for the next 2 weeks, I reply right away, she replied two weeks later apologizing for missing my time and ask me for the next 2 weeks I'm available. This went on for about a month. Finally I was passed to another recruiter, who responded a lot faster and scheduled my interview within a week.
The interview itself was technical, a couple programming problems and some OOP design concepts. I was asked to code on paper while explaining my thought process on the phone, which I always find hard to do, but I thought I did okay. I didn't have any problems with the coding itself.
I was contacted for a second round of interview a week later, and scheduled the interview 2 weeks after the call. It was another technical phone interview with Java concepts and programming problems. Unfortunately, the interviewer had a thick accent and the phone connection wasn't very clear (I heard a lot of background noises from his end) so I found it hard to understand him. He asked me about how to design the system at Amazon for displaying the availability of an item; this one I couldn't answer (more detail about the question below). I was also asked if I knew scripting languages/PERL. I was asked a little bit about my school projects, if there are any challenges that I faced, and asked about what I think is the hardest course.
Interview questions [5]
Question 1
How do you check if a Binary Tree is a Binary Search Tree?
Amazon has to display the availability of an item even when it's being viewed by millions of people. How would you design how this availability should be implemented so that it's as accurate as possible while being updated as quickly as possible?
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.
Um teste de código online, se aprovado, vai para o loop. O loop é 4 entrevistas seguidas, duas em inglês e duas em português. 3 entrevistas técnicas de código, todas as 4 têm pergunta de liderança.

Question 1
Pergunta historicas baseada nos principios de lideranca da amazon.
The whole process stretched over nearly a month, longer than I anticipated. After an initial phone screen, I faced a technical round that included a Min Stack implementation question. We discussed design considerations and thread safety, which threw me for a bit. Fortunately, I remembered a specific mock interview I practiced on PracHub that mirrored this scenario closely, making me feel more at ease. Ultimately, I received an offer, but I chose to decline due to the company culture not feeling like the right fit.
