I had an onsite interview with Snapchat for an iOS Software Engineer role. The interview process consisted of several rounds, including technical interviews, a coding challenge, and behavioral questions.

In the technical interviews, I was asked about my previous projects and experiences with iOS development. The interviewers were very friendly and encouraged me to ask questions.

For the coding challenge, I was given a problem to implement a feature for an existing iOS app. This involved both coding and designing the user interface, which I found to be quite engaging.

Overall, it was a great experience, and I felt that the interviewers were genuinely interested in my skills and knowledge. I am looking forward to their feedback soon!
