Read full description

SDET Interview Coach is the most comprehensive mobile interview prep app for Software Development Engineers in Test, QA Automation Engineers, and Test Engineers — from junior to staff level. Built by a 20-year SDET who has hired and been hired across Playwright, Selenium, Cypress, Java, Python, TypeScript, REST-assured, k6, JMeter, pytest, Jest, and AI-native testing. WHAT YOU GET • 800+ practitioner-grade SDET interview questions, sortable by seniority (Junior → Lead) and stack (Playwright, Selenium, Java, Python, TypeScript, AI-native) • Real mock interview scenarios — 8 to 15 questions in a timed session, mixed by difficulty, just like the real loop • Self-grading + spaced repetition — questions you got wrong come back at the right interval, so you actually learn instead of forgetting • AI feedback on every answer, written like a senior teammate at the whiteboard AI BOOTCAMP TRACKS (NEW) For manual QAs transitioning to SDET / Automation roles: • Playwright with TypeScript — the modern automation default • Playwright with Python — for Python-stack teams • JMeter performance testing • CI/CD pipelines for testers • API & contract testing Each track has scenario-based AI coaching that adapts to your level. Tap "Ask the Coach" inside any track for follow-up questions in plain English. JOB MATCH Paste a real job description and your CV. Get 25 bespoke interview questions tailored to the role plus a panel briefing on what to expect. 60-second turnaround. WEEKLY CHALLENGE Timed practice with the global community. New theme every Monday — drill on flaky tests one week, contract testing the next. ASK SDET COACH An AI tutor for any test-automation question. No more Stack Overflow rabbit holes when you're stuck on Playwright fixtures, Selenium waits, or k6 scripting. WHO IT'S FOR • Manual QA engineers transitioning to SDET / Automation • Junior SDETs prepping for their first promotion interview • Mid / Senior SDETs interviewing at a new company and shaking off the rust • Lead SDETs cramming for a system-design or framework-architecture round • Career changers entering software quality engineering THE QUESTIONS Each question has a short answer (the real answer, not a preview), a long-form explanation with tradeoffs and gotchas, code samples, follow-up questions the interviewer might ask, and watch-outs (anti-patterns to avoid). Written like a senior teammate, not a textbook. PRO FEATURES (£4.99/month after 7-day free trial) • Full 800+ question bank, refreshed nightly • Unlimited mock interviews + spaced repetition • Job Match — bespoke prep from any JD • AI feedback on every answer • All five AI Bootcamp Tracks • Monthly content drops as the SDET landscape evolves LITE PRICING Lower-income regions get the same core features at $2.99/month — because interview prep shouldn't be locked behind a Western salary.
