Resume phrasing

• "Led evaluation and adoption of Playwright for browser test automation, reducing test suite flake rate from 18% to under 1% and cutting execution time by 65%"
• "Architected migration strategy from Selenium WebDriver to Playwright, enabling parallel execution without Selenium Grid infrastructure"
• "Established browser automation standards and tool selection criteria based on architectural analysis of WebDriver vs CDP protocols"

Cover letter framing

"I approach tool selection as an architectural decision, not a preference. When our team's Selenium suite reached a 20% flake rate, I did not add more retries --- I analyzed the root causes, identified that 80% of failures were WebDriver protocol race conditions, and led the evaluation and migration to Playwright. The result was not just fewer flakes, but a fundamental shift in how our team thought about test reliability."

Interview framing

"When asked about browser automation tools, I start with architecture. Selenium uses HTTP round-trips per command --- find element, click element, check state, each a separate request. Playwright uses a persistent WebSocket connection with atomic operations. That architectural difference is why Playwright auto-waiting works and Selenium's explicit waits are a workaround. I have used both extensively, and the tool choice should depend on the team's context, but for new projects in 2026, the architectural case for Playwright is strong."

What not to say

• "Selenium is dead" --- it is not, and saying so shows you do not understand the legacy ecosystem
• "Playwright is better because it is newer" --- recency is not an argument; architecture is
• "I do not like Selenium because it is slow" --- this is vague; explain the HTTP round-trip overhead specifically
• "We should switch to Playwright because everyone is switching" --- bandwagon reasoning does not impress interviewers
