Interview Process

I prepared for the interview by reviewing common iOS development questions, particularly focusing on the Swift language and design patterns specific to iOS. During the onsite interview, I faced a series of technical problems, including a coding challenge that required implementing a feature for an iOS app using UIKit. The interviewers also asked behavioral questions about past team experiences and my approach to debugging complex issues. After the coding portion, there was a system design interview where I had to architect a new feature while considering scalability and optimization. Overall, the experience was thorough and I appreciated the challenging questions that tested my knowledge and problem-solving skills.
