11.7Interview Talking Point

"My approach to mobile and cross-platform testing starts with data: I pull device and browser analytics to build a three-tier testing matrix. Tier 1 devices -- typically 3 to 5 covering 60% of users -- run full regression on every PR. Tier 2 runs critical paths weekly. Tier 3 gets monthly smoke tests. For responsive design, I go beyond screenshot comparison by having AI agents resize viewports and verify functional correctness -- like confirming the hamburger menu appears at mobile widths and all navigation items remain accessible. For native mobile, I use Appium on cloud device farms like BrowserStack, and I am tracking Appium's evolution toward AI-native testing -- image-based element finding, the AI locator suggestions now built into Appium Inspector, and self-healing locators all reduce the maintenance burden that has historically made mobile automation brittle. I always include mobile accessibility in my test plans: VoiceOver traversal order, minimum touch targets of 44pt on iOS, and dynamic type testing at maximum font scale."
