I applied through my university's job board and was contacted by HR within a 3 days. Screening: The interview was conducted over the phone in a very casual manner. I was asked about my educational background and tested with a simple math flow question. Mainly, the interview was to inform me of what the position is about. Once you have confirmed to the interviewer that you want to proceed with the hiring processes, an on-site interview was acknowledged. The HR gave a few time slot options for the on-site interview and once accepted, study documents regarding the position is given. All travel bookings are taken care of by Amazon which was really awesome. My travelling situation was slightly different and the HR was very acceptive of the situation and gave be a step-by-step instruction in how to reimburse my expenses particularly. On-Site Interview: The on-site interview consists of 4 rounds of 30 minute one-on-one interviews. The interviewers consists of a local HR, 2 facility managers, and a regional manager. The order of the interviews are different since 4 candidates are rotated through the 4 interviewers. The questions are all behavioural/informative, but they can be difficult since some are extremely specific. One of the interviews is the math portion. All 4 candidates are given some time at the beginning of the process to work out a simple math flow question. During the interview, the candidates are asked to explain how did they arrive at the answers. Usually the initial question is simple and shouldn't cause anyone troubles. However, right after the steps are explained, the interviewer will change up the situation slightly to see how well one can think on his/her feet. This part gave me some trouble since I wasn't too familiar with how scheduling works and mainly I think I was just too nervous. If you are familiar with manufacturing plant scheduling and the concept of work time then it should be a breeze. Roughly a week later, the HR called to inform me that I was not selected for the job. The HR REALLY takes care of you. He brought snacks and drinks for us to the on-site interviews because he knew that the process involves a lot of talking. Also, the fact that he called personally to inform me of their decision shows how professional Amazon is. I have had too many so-called large companies leaving me hanging after interviews, so it is really nice for a change.
