Round1 - Coding round , 1) Merge k sorted linked list 2) Search in a sorted 2d matrix in O(m+n) time, the interview went well

Round 2- Coding Round, Given a list of flight departures and arrival, arrange the boarding passes, it was an interesting question , basically topological sort but cycles are allowed, the round went well

Round3 - High level design, asked to design a cloud based ML solution, I bombed this one big time

Round4- Bar raiser round, LLD round, was asked to write classes and design for amazon prime, this round was average since I did not get enough time to code (they ask behavior based questions for first half hour).

Keep in mind to answer behaviour based questions very precisely so that you get more time to code.
