Case Study: Design a Mobile App From Scratch
A full worked interview answer to a live 0-to-1 mobile design prompt — clarifying questions, JTBD framing, MVP scope, IA, wireframes, microcopy, accessibility, and HEART metrics, applying every earlier subject in the track
The capstone of the UI/UX Design Interview track: a complete model answer to 'design a mobile app that helps people find and book last-minute fitness classes near them' worked exactly as a candidate would in a 30-40 minute whiteboard interview — clarifying questions, JTBD over persona framing, an explicitly scoped MVP, bottom-tab information architecture, wireframe-level screens with Fitts's/Hick's Law reasoning, empty-state and booking microcopy, map-accessibility considerations, HEART success metrics, and a closing risk statement — synthesizing personas/JTBD, IA and navigation, wireframing, interaction design, UX writing, accessibility, responsive design, and metrics from earlier in the track.
