Amazon Transaction Risk Investigation interview questions

I appeared through pool campus drive. The interview process was supposed to start from 9:30 A.M. But it started at 12 P.M. It consisted of total 5 rounds and the whole process took two days. Patience is the ultimate skill for interview in Amazon. First round was JAM(Just a Minute) test, where HR asked me why do I want to join Amazon?? It was just to check candidates' communication skill. 2nd round was Watson Glaser test(Critical thinking test). But it was not very tough. Just Google the test and you will get an idea. 3rd round was typing test. 25wpm is sufficient to crack this round. 4th round was Pearson versant test(voice test). Who understands US and UK accent and read and speak English without any pause can easily crack this round. 5th and final round was Operation round/ F2F interview. The ops manager, who took my interview was very much open minded and energetic. I was the last guy in the interview, but the manager took the interview as if the 1st interview. My interview was supposed to start from 11:00 A.M. But it started at 9:45 P.M. The ops manager acted as a senior of my college and gave some valuable advice for my future. Overall experience was really awesome.
