Interview Process: Stage 1: HR round Stage 2: Phone screening Stage 3: Final loop (4 technical rounds) I did a deep dive into data structures and algorithms and personally solved over 700 problems in preparation. During the final loop, I successfully solved problems in 3 out of the 4 rounds. Unfortunately, one round focused heavily on trees and bit manipulation, which I struggled with, and that cost me the job. Overall, it was a very positive experience and a great learning opportunity.
