What We’re Looking For

• Strong CS fundamentals: You understand memory management, data structures, algorithms, and concurrency — and you know when to apply them

• Deep iOS expertise: You’ve built and shipped complex apps, and you know the ins and outs of UIKit, SwiftUI, and the broader Apple ecosystem

• Architectural thinking: You can design modular, testable systems and have opinions about MVC, MVVM, and beyond

• Curiosity and craftsmanship: You care about how things are built, not just what gets built

• Ecosystem fluency: You’ve worked with CI/CD, app signing, provisioning, Instruments, and understand the full lifecycle of an iOS app

• Clear communicator: You can walk through your own code and explain your decisions. You’re comfortable saying “I don’t know” and having a relaxed, technical conversation

• Collaborative mindset: You’re thoughtful, curious, and easy to work with — we try to keep it not so fussy

• AI maturity: You use AI tools to enhance your workflow — not to substitute for foundational knowledge


How We Interview

In our phone screen, you’ll walk us through three examples from your own code:

• Swift Language: We’re looking for depth — concurrency, generics, protocol design — not just syntax

• Apple APIs & Frameworks: Show us how you’ve used UIKit, SwiftUI, or lesser-known frameworks like AuthenticationServices or WebKit

• Apple Ecosystem: Talk about your experience with CI/CD, Xcode, performance tuning, app signing, crash analysis, or architecture decisions
