Mobile system design mock interview with Alexis Santos Perez

Practise designing a mobile app under interview conditions, with feedback on both your architecture and how you explain your decisions.

This session is for mobile engineers preparing for a system design or app architecture interview, especially for senior roles.

We'll work through a realistic mobile product problem. You'll clarify requirements, sketch the architecture and discuss trade-offs around data flow, networking, caching, offline behaviour and testing.

How we'll use the hour: 5 minutes to set the context, 40 minutes for the design exercise, and 15 minutes for feedback and questions.

You'll receive written feedback after the call with the strongest parts of your approach, gaps to address and a focused practice plan.

Before the session, share the target role, level and any guidance you've received about the interview. This session focuses on the mobile client and its API interactions. It doesn't cover a full backend infrastructure interview.
