The interview consisted of two parts. The first part was a coding challenge where I had to solve problems within a set duration. The second part was a system design interview where I had to design an application architecture based on given requirements. I encountered several questions that required a deep understanding of algorithms and data structures. Overall, the experience was quite intense but rewarding.
