50+ Azure Data Factory Interview Questions and Answers 2025

I was responsible for setting up RabbitMQ clusters, configuring exchanges, queues, and bindings, as well as monitoring their performance. This implementation not only enhanced the overall performance but also contributed to better scalability and resource management for the platform.” Additionally, we set up cache expiration policies to ensure that the stored data remained up-to-date and relevant. We used Redis as our caching solution, which allowed us to store key-value pairs of product IDs and their respective data. For instance, in a previous project, I worked on an e-commerce platform with a large product catalog and high traffic volume.
Their unique Engineering First approach blends deep industry expertise and empowered, agile teams, to create holistic solutions that seamlessly move the business forward. Virtusa provides domain expertise and technical skills to transform any business at a very large scale with good speed. A configuration file in Playwright is a crucial element that helps streamline the testing process by defining various settings and parameters for your test runs. CodeSignal Learn is a learning platform for anyone launching a career, pivoting into a new role, building competitive and in-demand skills for a job search, or leveling-up in their current role. This assesses the ability to connect models to views and configure URL patterns, essential for building Django web applications. An example is provided for creating an instance of Book in the Django shell, including saving it to the database.
The hybrid nature empowers teams to tailor the framework to suit their specific needs, adapting to various types of applications and testing scenarios. This allows testers to use keywords to define actions and scenarios, while also enabling the reuse of these keywords across multiple data sets for broader test coverage. By abstracting the implementation details, a keyword-driven framework enhances reusability, maintainability, and overall clarity of the automation tests. This approach allows testers to write tests without deep knowledge of the underlying code, making it accessible to both technical and non-technical team members. By understanding and mastering these advanced Python concepts, experienced developers can improve their coding https://uvik.io/ efficiency and problem-solving skills. It provides functions to parse JSON strings into Python objects and convert Python objects into JSON strings.

If we do not want to delete the EBS volumes after the termination of EC2, we can use the attribute deleteOnTermination and set it to ‘false.’ When an EC2 instance is terminated, it also shuts down in a usual way. Due to the standard shutdown, EBS volumes remain in the instance, and we can restart the instance anytime. The standard procedure of shutdown leads to a stopped state of the instance.

How would you handle authentication for APIs that use API keys?

Scrolling is an essential part of web interaction, especially when dealing with long pages or dynamically loaded content. This functionality ensures that your automated tests can effectively interact with all types of web page dialogs, mimicking real user behavior while navigating through your application. To ensure a comprehensive approach to dialog management, you can use the `page.on(‘dialog’, …)` event listener as previously mentioned.
Semaphores maintain a set of permits; a thread can acquire a permit (if available) or release it back to the semaphore. For instance, if we want Thread B to execute after Thread A, we call B.join() in A’s run method. One common method is to use join(), which makes a thread wait until the completion of another. Thread execution order can be controlled using synchronization techniques. It’s essentially a variable that maintains a count of available resources, or slots. A semaphore in multithreading is a synchronization tool used to control access to shared resources.

First, it is essential to thoroughly understand the API documentation provided by the third-party service to ensure correct implementation. This could involve checking for a success message, the presence of the file in a list, or any other confirmation the application provides. We should implement this interface creating a listener class of our own. Page object model (POM) can be used in any kind of framework such as modular, data-driven, keyword driven, hybrid framework etc.

• Now, let’s talk about Python’s virtual environments.
• I believe that such knowledge exchange will prepare me for more challenging projects.
• Participation in Python community events, contributing to libraries on GitHub, or creating Python packages can enhance a developer’s resume.
• Which ServiceNow feature allows users to build applications with minimal coding?

Reporters can be easily configured in the Playwright configuration file, giving testers flexibility in how they visualize and analyze test results. Furthermore, Playwright also supports custom reporters, allowing developers to create tailored reporting solutions that fit specific needs or formats. By default, it comes with a built-in “List” reporter that outputs results to the console in a simple list format. The options include ‘load’, ‘domcontentloaded’, ‘networkidle’, and others, depending on your specific needs for the test context. This enhances the reliability of your tests by ensuring elements are ready for interaction before proceeding.
It also makes programming easier since developers don’t have to worry about unexpected context switches. This gives each thread more control over its execution but can lead to issues such as starvation if a thread refuses to yield. Non-preemptive multithreading, on the other hand, requires threads to voluntarily yield control of the CPU. This is beneficial in preventing a single thread from monopolizing CPU time and ensuring fairness among all running threads. Preemptive multithreading allows the operating system to control thread execution, switching between threads without their consent.
They should demonstrate a good understanding of handling large datasets efficiently. Ensuring that both environments are as similar as possible is crucial. To identify mid-tier developers who are adept at debugging Python, refer to this list of intermediate debugging questions. They help evaluate candidates’ ability to identify, troubleshoot, and resolve common coding issues. To assess junior Python developers’ debugging skills effectively, use these 20 interview questions. They might also talk about looking for common culprits like circular references or objects that are not being garbage collected.
