• File Upload Strategies – Interacting with native OS dialogs versus using the sendKeys() method on hidden file input elements.
• Dynamic Web Tables – Writing algorithms to iterate through rows and columns, locate specific cell data, and perform actions based on table contents.

Example questions or scenarios:

• "Write a code snippet to locate a specific row in a dynamic table where the unique identifier is in the third column, and click the edit button in the last column."
• "How do you handle a scenario where a file upload button does not have an input tag with type='file'?"

Locator Strategies & XPath Axioms

Writing resilient locators is the foundation of robust automation. You must prove that you can navigate complex, dynamic DOM trees without relying on brittle, auto-generated paths.

Be ready to go over:

• XPath Axes – Utilizing relationships like sibling, parent, ancestor, and descendant to locate elements relative to stable anchors.
• Dynamic Attributes – Using functions like contains(), starts-with(), and logical operators to target elements with shifting IDs or classes.
• CSS Selectors vs. XPath – Understanding the performance differences and functional limitations of each locator strategy.
• Advanced concepts (less common) – Custom locator strategies, shadow DOM navigation, and handling nested iframes.

Example questions or scenarios:

• "Explain how you would write an XPath to target a checkbox that is next to a label containing specific dynamic text."
• "How do you interact with an element that is nested inside multiple shadow roots?"

Test Framework Design & Architecture

For senior or mid-level roles, the team will evaluate your ability to design, maintain, and scale automation frameworks from scratch.

Be ready to go over:

• Page Object Model (POM) – Designing clean page classes, separating page elements from test assertions, and managing page initialization.
• Data-Driven Testing – Integrating external data sources (like Excel, JSON, or databases) into your test execution pipeline.
• Reporting and Logging – Implementing robust logging frameworks and generating actionable test execution reports for stakeholders.

Example questions or scenarios:

• "How would you refactor a legacy test suite that has hardcoded wait times and duplicate element definitions?"
• "Describe how you design your framework to run tests in parallel across different browser configurations safely."
