I applied online by submitting my CV and taking an online assessment which consists of behavioral questions to test you how well you align with the Leadership Principles and to see how you work. The application process was hassle-free and the recruiter reached out fairly quickly, less than a week after, and provided lots of details and had already an interview call scheduled in advance.
Next step was the interview loop of 3 back-to-back interviews what were very tough but exciting. My interviewers were very bright individuals, nice, supportive, understanding and clearly showed that they like their jobs a lot, which made me want to work at Amazon even more. At times I struggled but they remained kind, supportive and clearly wanted me succeed. Amazon does a very good job preparing you for this loop and there is lots of information online. I recommend that you attend the prep call the HR sets up every Friday (you'll get a link if you are selected).
I had 2 interviews where the interviewers asked me behavioral questions and I needed to provide exemples from my professional experience and answer the question using STAR method. I applied for the role in Paris, and 2 of my interviewers were based in England and another one was from Paris. 2 of them were conducted in English and another one was conducted in both French and English. The questions are based on the Leadership Principles, so the answers should also call for them. Some questions might sound strange or too high-level for entry-level roles (I interviewed for an associate level position that only required 1 year of experience) and the interviewers admitted multiple times that they are phrased a bit weirdly and told me not to focus too much on the wording. My advice for preparation is to first review the Leadership Principles and see how your experiences and maybe your own work philosophy or personality align with them. Then, prepare stories from your past experiences and practice answering questions in this way beforehand, it will definitely be appreciated as this is what they expect. My another advice is to provide as much data as you can, it can be results or scale, it's very appreciated by Amazon.
My last interview was a case-study which had to be done in real time. The interviewer sent me an Excel file and shared their screen with instructions and some context. They give you all the information you need to do well. I made a few mistakes but the interviewer said that it's okay and we walked through the case study together after the 25-minute prep time ran out. I don't think the case study needs to be necessarily "solved", the whole point of it is to see your reasoning. If you make mistakes, they will not take off points because they also want to see how you react to making mistakes and what you do to get back on your feet. In other words, for my case, the journey was more important than the destination. The tasks were: 1) complete columns using provided formulas, 2) identify top 5 products to which 200k marketing budget should be allocated to, based on criteria, 3) identify bottom 3 products that need immediate action.
I thought I didn't do a very good job during my interviews but the recruiter called me the day after to tell me that the feedback was positive and that I passed the loop which made me very happy. However, they were unable to make me an offer right away as it turned out that there were no more places available for the position I applied for, which was disappointing. The recruiter promised to check in during the next month to let me know if there are any updates.
Overall, it was a very pleasant, challenging and smooth experience. If you want to work at Amazon, please take the preparation seriously because the Leadership Principles are not a joke and people who work there really do live and breath the LPs on a daily basis and the interview loop is mostly about checking whether you do too.
