Interview Process

During the interview process with Snapchat, I faced a series of technical and behavioral questions that tested my skills thoroughly. The first part of the interview focused on data structures and algorithms, where I was asked to solve a problem related to arrays and strings. I solved it while discussing my thought process, which they seemed to appreciate.

After some coding questions, the interviewer shifted gears to ask about previous projects I’ve worked on. They were particularly interested in my role in a team project and how we handled challenging situations, emphasizing teamwork and problem-solving.

The final part of the interview was dedicated to system design. I was asked to design a real-time chat application, which required me to think about scalability and the choice of technologies. This was a challenging but rewarding experience that allowed me to showcase my understanding of system architecture.
