Amazon Sr. Program Manager interview questions

Was found via a recruiter on LinkedIn. Received email asking if I would be interested in a phone screen. From there, I was scheduled to interview with the hiring manager over the phone. HR seems to be a little confused when scheduling and coordinating said interviews. (times/dates incorrect) Interviewed with hiring manager over the phone then interviewed with a vertical team member. About 3 days later I was invited to come onsite and interview for a full Amazon loop. An Amazon loop consists of 6-7 different people with an average time of 45 minutes. Most of the individuals in my loop were genuinely nice and asked clear and concise questions. The downside of this is that they pretty much all asked the same question over and over again. Some of the questions are rudimentary in nature, but leaves an environment of openness for the interview. The Amazon interview process also has an individual who is called 'the bar raiser'. This employee is almost cold to a certain degree and gives brick wall questions. Don't feel discouraged by this person as they want to see how you handle pressure and analytical thinking. Be prepared to interview for a solid 7 hours. Prepare as much as possible beforehand, but don't come off sounding as though you scripted anything. Overall, just be yourself and be patient with the process.

Two rounds of telephonic interview. Lots of practical projects related and entrepreneurial questions. Enjoyed it thoroughly. Covered daily project management activities, risk assessment, questions about building a credit card rewards system and pricing system for returned warehouse items, most difficult technical challenge, net present value, risks of a book store.
