The process is uniquely designed to assess both your technical capabilities and your ability to integrate into a distributed, transitioning team.

Your journey will begin with an initial HR phone screen. Unlike many companies where this is a simple logistical check, the HR screen at Arthrex acts as a strict gatekeeper. The recruiter heavily evaluates your communication skills, motivations, and cultural fit; if you do not impress at this stage, you will not move forward. Following this, you will have a conversation with the hiring manager to discuss your background, team fit, and high-level technical experience.

The technical evaluation is split into multiple phases. You will face a rigorous technical screening with a software development supervisor—often based out of the Naples, Florida mobile hub—which dives deep into iOS fundamentals. Finally, because of the ongoing effort to bring external apps in-house, you will likely have a technical discussion with the external agency developer currently responsible for the app. This step is highly unique and tests your ability to understand existing architectures, ask insightful questions, and handle technical handoffs professionally.

This visual timeline outlines the progression from the critical HR gatekeeper screen through the hiring manager interview, the core technical evaluation, and the final agency sync. Use this to pace your preparation, ensuring you are ready to articulate your cultural alignment early on before shifting your focus to deep technical and architectural discussions in the later rounds. The split technical rounds mean you must be prepared to discuss code with both internal supervisors and external contractors.

To confidently navigate the technical rounds at Arthrex, you must understand exactly what the engineering supervisors and external developers are looking for.

iOS Foundations: Swift and Objective-C

Because Arthrex is migrating externally developed applications in-house, their codebases often contain a mix of older and newer technologies. You must demonstrate that you are not just a modern Swift developer, but someone who understands the historical context of iOS development.
