Amazon Senior Software Engineer interview questions

An initial 90 minute technical test followed by 6 hours of interviews. 3 were technical interviews and 2 were leadership and how I work. The interviews all asked the same questions making it difficult to give a unique answer to each question. It seemed very disorganised between interviewers. 2 interviewers gave good impressions, one clearly decided he didn't like me from the start.

Too much coding involved...questions similar from leetcode...felt tough but can be cracked with adequate preparation....didnot land an offer.....need to prepare for system design, coding, behavorial and other stuffs ... best to be prepared
