Whether a beginner or a seasoned professional, these interview questions on Azure Data Factory can help you prepare for your next Azure data engineering job interview. Here we shared top ADF interview questions and hope they will help you prepare for your next data engineer interview. With the ‘Copy’ activity, data can be moved between various source and sink data stores, including Azure Data Lake Storage, Azure Blob Storage, and Azure SQL Database. Linked services provide a way to specify the account name and credentials for the first two data sources to establish a secure connection.
Headless browser testing runs automated tests without displaying the browser’s graphical interface. That’s where Selenium and Cucumber come in, working together like a dream team for web testing! Imagine trying to explain test scripts to your boss who doesn’t know code? Selenium itself does not directly support database testing because it is designed for UI automation. Synchronization in Selenium ensures that WebDriver interacts with web elements only when they are available and ready for the required action, especially in dynamic web applications.
It is different from a regular function in that it uses the “yield” keyword to return values one-at-a-time instead of returning a list of all values at once. You’ll also find a set best practices to ensure your interview questions accurately assess the Python skills of your candidates. In order to access variables in an outer scope the nonlocal keyword is required, and in order to reference variables in the global scope the (you guessed it) global keyword is required. Work through the code examples, build a small POM-based project with fixtures and a GitHub Actions workflow, and you’ll walk into any QA or SDET interview prepared for whatever tier they start at. Choose Cypress when your team is JavaScript-only, you want a rich subscription dashboard with time-travel debugging, and you’re testing primarily Chrome.

• It is a command-line tool providing a seamless interface for installing different python modules.
• Demonstrating your experience in successfully collaborating with frontend developers highlights your adaptability and commitment to creating high-quality products.
• A strong candidate should emphasize the importance of reproducing the issue consistently and using a combination of logging, debugging, and testing techniques.
• The code is correct and will sort the list of dictionaries by the age key.
• At the beginning of each day, I prepare a to-do list where I list out everything that needs my attention before embarking on them based on their urgency and deadlines.

What is the difference between Monolithic and Microservices Architecture?

It creates the objects, configures and assembles their dependencies, manages their entire life cycle. In a nutshell it’s a library that can be utilized and customized to suit the demands of the programmer. Spring Security is a framework that https://uvik.io/ allows a programmer to use JEE components to set security limitations on Spring-framework-based Web applications. In Spring Boot, by default, the applications are accessed by context path “/”. The context path is a prefix to the URL path used to identify and differentiate between different context(s).
Because of the @Factory annotation, the test methods in class TestClass will run twice with the data “Dataset1” and “Dataset2”. We need to set some wait time to make WebDriver to wait for the required time. Both sleep() and setSpeed() are used to delay the execution speed. By understanding and leveraging context nodes, testers can create more robust and maintainable test scripts.

Why might a feature work in testing but fail for real users?

LastRoundAI’s Interview Copilot runs live during real interviews and feeds structured, real-time guidance on exactly this kind of follow-up, sub-200ms and invisible on a screen share, so you’re not reconstructing an OAuth flow from memory under pressure. Reading through a list of API developer interview questions is not the same as defending an answer out loud when an interviewer changes one detail on you mid-response. Across mock interviews tagged “API design” in LastRoundAI’s Interview Copilot logs this year, the single question pair candidates fumble most isn’t OAuth or GraphQL. The fix there is making sure backend keep-alive timeout is set longer than whatever sits in front of it, not shorter, which is the opposite of what a lot of default configs ship with. The other common cause is a keep-alive or timeout mismatch between the load balancer and the backend.
