About

SDET Interview Coach

Features
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.
