Interview Process

I recently had an onsite interview for a Software Engineer position at Snapchat. The interview was structured into multiple rounds, including coding, system design, and behavioral questions. The coding round focused on data structures, algorithms, and real-world problem-solving using Swift. I felt prepared due to my practice with LeetCode and similar platforms. The system design section required me to outline the architecture for a mobile application, and I was asked about scalability and performance. The behavioral interview delved into my past experiences working in teams and handling conflicts. Overall, the interview experience was quite engaging and challenging, and I appreciated the interviewers’ friendly attitude throughout the process. I felt like I was given a fair opportunity to showcase my skills and thought process.
