First Round--> 20 general apti, 40 os/networking/dbms mcq, 2 coding questions I was able to clear with 1 coding question and a decent score in mcq's. The mcq's are the real key here. Each section has an individual cutoff. This is followed by 4 rounds of f2f interviews . f2f round1: Questions mainly focussed about OS and Networking Depths with basic coding questions round2: Detailed logical Networking OS concepts and practical questions related real life problems. (Basicallly a bar raiser round) round 3: hr+technical focussed more about extra curricular activites, why you want to join amazon and little troubleshooting questions like Windows BSOD error. round 4: managerial round on why you wanna join amazon, what values will you bring to AWS.
