Compare Languages for QA Automation

Context

QA automation engineers are often expected to justify which programming languages they can use effectively and why. Interviewers usually care less about a raw list of languages and more about whether you understand the trade-offs behind choosing one for a test automation stack.

Core Question

Explain which programming languages you are proficient in for QA automation, and compare them from an engineering perspective. In your answer, address:

1. Which languages are commonly used for UI, API, and mobile test automation
2. What factors influence language choice, such as ecosystem, readability, team skill set, and CI/CD integration
3. How you would decide between languages for a new automation framework

Scope Guidance

The interviewer expects a structured, practical explanation rather than a personal résumé summary. Focus on language characteristics, common tooling, maintainability, and how your choice affects automation design and long-term support.
