I applied for the job through LinkedIn and received an email a few weeks later telling me that I made it to the next step of the interview process. I was then asked to fill out a survey which was pretty easy and you could tell what answers they were looking for. After the survey a few days passed before I was sent an email telling me that I was not selected to make it to the next step in the process but that same day I was sent another email saying that they would like to offer me an interview opportunity, I thought the hr person made a mistake so I sent them a email letting them know that they must have accidentally sent me the email since I received one earlier that day telling I was not selected. After that a few more days passed and then I was sent another email saying they would like to offer me another interview and that this was their second time trying to interview me but I never received an email from the Hr person letting me know whether or not the first email was sent to me on accident or not. I then accepted the interview and started to set up travel arrangements through Amazon. The interview consisted of me meeting with someone who went over the process and helped me relax I was also given the math problem at this time. I then had an interview with two guys who worked in the Operations Manager job they asked me about my qualifications. My next interview I was interviewed by one person and we just went over the math problem. After that the interview was over.
