Amazon Device Associate interview questions

The interview process went virtually from home and I attended 3 rounds of the interview and got rejected (Chennai) (Device Associate, Fire OS) 1. Online written test :- Aptitude and English ( it was a very easy round) 2. Technical interview 1 :- (went for 20 mins) Questions related to manual testing and test cases and scenarios of apps were asked. ( i performed below average in this round and i answered only 50% of the questions) I am from Mechanical. But i got email for the next round, i was so excited and doesn't wanted to repeat the same bad performances So I prepared for 2 days straight just like preparing for a semester exam 3. Technical interview 2 :- (went for 33 mins) Questions related to SDLC, STLC, manual testing, defects,bugs, test cases, test scenarios etc were asked ( i performed very well in this round and answered 100% of the questions with detailed explanations and examples) The interviewer was expecting direct 1 line answer for every question So when i start to explain he stops me and told me to say the direct answer (It was irritating to me) but i did well and the final words of the interviewer was also good But after 5 days i got the Rejection mail and i was so disappointed (I think they compute your performances based on both the technical interviews) So i will again apply after 6 months
