The interview consisted of two parts: coding and system design. In the coding interview, I was asked to solve a problem involving data structures and algorithms, specifically focusing on arrays and hash maps. The interviewer was friendly and provided guidance when I got stuck.
For the system design portion, I was asked to design a simplified version of an ad serving system, considering aspects such as scalability and latency. I discussed my approach to handling failover scenarios and data persistence. Overall, it was an engaging experience and the interviewers were understanding. I felt comfortable asking questions and clarifying requirements throughout the process.
