Read test data from external sources (like CSV or Excel) and run tests with different data sets. For I/O bound tasks (like file operations or network), use multithreading or asynchronous code to improve performance. Conditional statements control the flow of execution using if, elif, and else. The __slots__ feature limits which attributes can be added to instances of a class to save memory, since a dict is not created for each instance These questions frequently pertain to algorithms, system design logic, and data manipulation and allow you to demonstrate that you can write clean, efficient, and easily scalable code under pressure.
Due https://uvik.io/ to its simplistic nature and the ability to achieve multiple functionalities in fewer lines of code, python’s popularity is growing tremendously. Python also supports object-oriented programming and is most commonly used to perform general-purpose programming. It is one of the most widely used and loved programming languages and is interpreted in nature thereby providing flexibility in incorporating dynamic semantics.

//Simulate enter key action robot.keyPress(KeyEvent.VK_ENTER); They are commonly used when we want to perform multiple assertions. Soft Assertions are customized error handlers provided by TestNG. In this file, we can create a test suite, create test groups, mark tests for parallel execution, add listeners, and pass parameters to test scripts. Use iMocha and create custom skills assessment to hire job-fit candidates and reduce time to hire by 50% JDBC (Java Database Connectivity) API is required for database testing in Selenium Webdriver.
It adds a Test Explorer panel listing all discovered tests. Adding a storageState reset to beforeEach caught 80% of our intermittent failures on a 300-test suite. In practice, the most common source of flakiness in Playwright suites isn’t Playwright itself – it’s shared browser state leaking between tests.
- For instance, if we want Thread B to execute after Thread A, we call B.join() in A’s run method.
- Probe for their favourite technical books.
- A class typically contains attributes (variables) and methods (functions) to define the behavior of objects instantiated from the class.
- Lambda is typically utilized when an anonymous function is required for a short period.
Additionally, I have experience in automating deployments using CI/CD pipelines, which further enhances the reliability and speed of application delivery. My work involved deploying applications using Kubernetes manifests, configuring services and ingress controllers for load balancing, and setting up monitoring tools to track cluster performance. My experience with Docker includes creating custom images using Dockerfiles, managing containers, and setting up private registries for secure storage of images. This approach also promotes faster development cycles since teams can work on different microservices simultaneously, allowing for more agile responses to changing requirements.
You only access SparkContext directly when you need to work with RDDs or set low-level Spark configurations. When you create a SparkSession, Spark automatically creates an underlying SparkContext that you can access via spark.sparkContext. SparkSession (available from Spark 2.0 onwards) wraps SparkContext and also provides access to DataFrame, SQL, and Streaming APIs. SparkContext (often written as sc) is the original entry point to Spark functionality. If you have too few partitions, some nodes sit idle and your job runs slower than it should.
How Karat seems to score and evaluate candidates
It provides a minimalistic framework for building small to medium-sized web applications, allowing developers to choose and configure only the components they need. It provides a full-featured toolkit for building robust web applications, including features like an ORM, authentication, and administration panels. Nevertheless, rather than building all functionality into its core, Python was designed to be highly extensible through modules. Mapping data flows provides an entirely visual experience with no coding required. Using it, companies can efficiently operate their tasks and build solutions as per their requirements. Long Nguyen is a fullstack developer at Netalith, covering a broad range of technical and business topics — from AI systems and SaaS architecture to SEO and e-commerce strategy.
Mastering these 10 questions prepares you for both technical and behavioral rounds. This blog explores 10 essential Python interview questions that assess your technical strength, system-thinking, and real-world readiness. We set this handler by calling the setUncaughtExceptionHandler method on our thread instance and passing an instance of a class implementing UncaughtExceptionHandler. In multithreading, exceptions are handled differently than in single-threaded environments. We could also use formal methods like model checking to mathematically prove properties about our concurrent program. Another technique is atomic operations, which complete in a single step without being interrupted.
