This was a process that took over 6 weeks. I was reached out by a recruiter for a position that I did not apply for. The recruiter had a questionnaire, shortly after they set up a prep phone screening call which is optional. I then had a phone screening with the hiring manager. The manager only asked me two behavioral questions and was more interested in what my previous role was. I then had a second phone screeing. Which was focused on two behavioral-based interview questions and leadership principles. I then had a group prep video conference call prior to the final round of interviews. The final round of interviews was 5 in one day spread out over 8 hours. Two of the interviews had interview shadowers. I was told that there would be no excel based assessment yet on my second interview the interviewer pulled up a spreadsheet and wanted me to answer questions on it which I was not prepared for since, both prep calls and the recruiter had told me this would not be the case. All of my behavioral-based interview questions were so focused on how I built out spreadsheets from years ago and I did not study or practice for this. I thought all I need to do was explain the process but they wanted me to go in-depth and talk about formulas, which I also had an NDA for. They claim to understand this but it really didn't seem like they did and honestly, I felt like the fact that I wasn't breaking an NDA was held against me. Whether it was or not I'll never know. Personally, no matter how much they pay I would not go through this process again even if I was paid to do so. If you don't get the job you've wasted way too much time. If you are interested in working at Amazon not only should you study behavioral-based interview questions (there are many amazon interview prep sites, you should also read working backward book), the leadership principles, but also study every single one of your previous employer's processes. And do not under any circumstance use an example more than once, they say you can do this but I can tell that they did not like that. They also did not want me to use any examples from my Master's Capstone or Internship and were solely focused on a job I did two years ago.
