Amazon For Business Analyst interview questions

Recruiter made a couple of calls prior to confirm my availability for the interview, When I arrived at the site, I am impressed by their hospitality. I was asked to take up a written test which lasted for about 2 hours. When its complete, They gave me the feedback within 10 minutes. The second round of interview was 1:1 with another analyst on couple of business reporting scenarios (SQL). After its done, I got a break of 1 Hour for lunch The third round of interview was 1:1 with another analyst on couple of data loading strategies. Looks like this guy got a little bit of ego The fourth round was 1:1 with the manager, evaluating my attitude and couple of questions on SDLC and project architectures. Later after that, I was asked to leave for the day & wait for the feedback. After 1 week I got the reply saying We hope you are doing fine!
