Interview Process
I had an onsite interview with Snapchat for an iOS Software Engineer position. The interview consisted of several technical rounds, along with behavioral questions.
In the first round, they tested my understanding of iOS frameworks and asked me to explain how I would implement a feature using Swift. I was asked about memory management and handling app lifecycle events.
The next round focused on algorithms and data structures, where I had to solve problems related to arrays and strings. They asked me to optimize a solution for a common problem.
The final round involved system design, where I had to design a scalable application and discuss aspects like database choices and microservices architecture. The questions were quite challenging but reasonable given the position.
Overall, the experience was rigorous but very informative. I appreciated the depth of the questions and the technical focus throughout the process.
