About Masterclass

Landing an SDET role takes more than writing a few Selenium tests—it demands solid coding chops, deep testing fundamentals, and the ability to reason about systems at scale. This masterclass maps the full journey: polishing your Java/Python Web-UI scripts, leveling-up to API and back-end automation, and finally demonstrating the architectural “big-picture” thinking that top companies probe for in interviews.

Masterclass Outcomes

Live Coding Drill: Automate a “search then add-to-cart” flow, refactor to page objects, and optimize waits—all under time pressure.
Test-Design Whiteboard: Sketch a strategy for a payments microservice—covering unit, contract, integration, load, and chaos tests.
System Design for SDETs: Outline a scalable test farm (Docker-Selenium grid + API stubs + data seeding) in 15 minutes.
Behavioral Storytelling: Framework to answer “Tell me about a time you improved test reliability” with STAR precision.
