Apple Product Designer Case Interview — Ecosystem UX with HIG, Privacy, and Accessibility
This case simulates a real Apple product design exercise focused on crafting a simple, elegant experience that works seamlessly across the Apple ecosystem (iOS, iPadOS, watchOS, macOS, tvOS). The session reflects Apple’s interview style: clarity of thought, taste and craft, deep respect for the Human Interface Guidelines (HIG), privacy-by-design, accessibility-first, on-device performance, and close cross‑functional collaboration with engineering and product. What you’ll work on (choose one prompt during the interview): - Apple Music: Design a cross‑platform feature that helps users rediscover owned or saved content with minimal cognitive load, while preserving on‑device personalization. - Apple Pay/Wallet: Streamline an offline transit flow that is fast, private, battery‑efficient, and resilient in edge cases (dead battery, lost device). - App Store: Improve subscription transparency and cancellation discoverability without adding friction to legitimate purchases. - Health/Fitness+: Create a light‑touch nudge to increase daily movement that adapts across iPhone and Apple Watch, respects sensitive health data, and avoids notification fatigue. - Apple TV+: Design a kid‑friendly profile handoff that keeps continuity with adult profiles while enforcing content restrictions and simplicity. Agenda and timing (typical Apple cadence): - 0–5 min — Context: Role, target user, success definition, constraints. You drive clarifying questions; avoid assumptions that violate HIG or privacy principles. - 5–20 min — Problem framing: Jobs-to-be-done, user segments, scenarios, guardrails. Identify the single most important user outcome and the minimum lovable path. - 20–45 min — Solution exploration: Sketch primary flows and core screens; show how the design adapts per platform (e.g., watchOS glanceability, iPadOS multi‑window, macOS menu bar patterns). Call out haptics, motion, and states. - 45–60 min — Depth and edge cases: Failure modes (offline, poor sensors, family sharing, lost device); privacy (on‑device processing, least data, user consent); accessibility (Dynamic Type, VoiceOver labels, color/contrast, touch targets); internationalization; performance and battery. - 60–70 min — Trade‑offs, metrics, and rollout: Define success metrics (task success, time to completion, opt‑in/opt‑out rates), experimentation approach that protects privacy, technical risks, and a phased release plan. Apple‑specific expectations and constraints: - HIG alignment: Clarity, deference, depth. Use native components, SF Symbols, system typography, and platform‑appropriate navigation. - Privacy & security: Default to on‑device processing, minimal data collection, transparent controls, and clear benefit for any permission. - Accessibility as a first‑class requirement: Design with Dynamic Type, VoiceOver, switch control, motion/contrast settings, and haptic affordances. - Performance and battery life: Favor lightweight interactions and efficient animations; consider low‑power modes. - Ecosystem continuity: Handoff, iCloud sync, family sharing, offline behavior, and recovery paths must be intentional and simple. - Feasibility: Show how you’d partner with engineering on APIs/SDKs (e.g., HealthKit, Wallet, Nearby/UWB, Secure Enclave), identify tech dependencies, and reduce complexity. Deliverables during the session: - Problem statement and single prioritized user outcome. - Primary task flow and 2–3 key wireframes (lo‑fi is fine) with platform adaptations. - Edge cases and system states (loading, error, empty, success). - Accessibility, privacy, and performance callouts embedded in the flow (not bolted on). - Success metrics, experiment design, and phased rollout strategy. Evaluation rubric (Apple bar): - Product sense (clarity, prioritization, simplicity over configuration). - Craft and taste (information architecture, hierarchy, motion/haptics, polish under time). - Systems thinking (ecosystem coherence, platform variations, state management). - Privacy, accessibility, and performance (first‑order considerations, not afterthoughts). - Technical collaboration (trade‑offs, feasibility, API awareness, concise rationale). - Communication (structured, crisp, visually clear; strong use of whiteboard/figma shorthand). Red flags: Over‑custom components that fight the HIG, data‑hungry or permission‑gated flows without clear user value, accessibility as an afterthought, solutions that don’t scale across devices, or hand‑wavy metrics/rollout.
