Interview Process
The interview process was quite rigorous. It started with a phone screen that focused on behavioral questions. After clearing that round, I was invited for an onsite interview, which consisted of four rounds: two technical interviews, one system design, and one behavioral round.
In the technical interviews, I was asked to solve problems primarily based on algorithms and data structures. They used a whiteboard for the coding part, and I had to explain my thought process clearly while coding. The topics covered included trees, graphs, and dynamic programming.
The system design interview focused on designing features like a social media sharing functionality and included discussions on database choices, server architecture, and scalability. Finally, the behavioral interview assessed my motivations, teamwork experiences, and how I handle challenges. Overall, I felt the process was fair but challenging.

Tips & Insights
Be prepared to explain your thought process during coding, and ensure you have a strong understanding of algorithms and data structures. Familiarize yourself with system design principles, especially in the context of social media functionalities.
