Key Python Interview Questions From Basic To Senior Level

I designed the backend with Spring Boot, added a MongoDB database, implemented user sign-in, and designed the REST endpoints. Fresher candidates walk into the EPAM interview feeling they are right on the track where the knowledge they have gained will meet the skills they have practised. After a managerial or systems design interview, an HR interview, which focuses on the candidate’s overall communication skills, cultural alignment, professional goals, and expectations on the role, follows. The candidate’s Java and Object-Oriented Programming knowledge, design patterns, databases, systems, and even their previous projects are evaluated during one or two technical interviews as well. Recently, in May 2025, the company’s founder, Arkadiy Dobkin, is set to become the executive chairman of the board on the 1st of September and hand over the CEO position to Balazs Fejes. Earning a position at EPAM Systems, one of the top-tier global IT consulting and software engineering firms, requires extensive mastery of data structures, algorithms, problem-solving, systems design, and soft skills.
A Reddit thread on Karat interview questions described the experience as “very basic” with LeetCode-easy coding and very simple system design. The recurring coding questions are usually not wild LeetCode hard problems. Be ready to explain race conditions, locks, deadlocks, and where concurrent code becomes hard to reason about.
It shows you understand that internationalization bugs are browser-context bugs – not just translation bugs – and that Playwright surfaces them without device farms. It’s faster than full E2E tests and more realistic than JSDOM-based unit tests (Jest, Vitest). Teardown is automatic and runs in reverse dependency order. The registration-before-trigger pattern is the most common mistake at this level.

What is MERN Stack?

Consistent practice on these platforms helps you get familiar with the types of questions asked in interviews and improves your problem-solving speed. You will find benefits by leveraging coding challenge websites (LeetCode, HackerRank, CodeChef) to practice questions across different difficulty levels. Combining hands-on experience with regular practice of Python technical interview coding questions can significantly improve your interview performance.

• This helps in providing a better end-user experience.
• This involved configuring build triggers, creating test scripts, and deploying code to various environments such as staging and production.
• This tests your communication skills, which is huge in a karat interview.
• To excel in Python coding challenges, theoretical knowledge must map to practical application.

What Do You Understand By A Stack?

Playwright can also be utilized for performance testing, ensuring that applications meet speed and responsiveness expectations. Primarily, it excels in end-to-end testing, allowing users to test the complete functionality of web applications from the user’s perspective. With features like auto-waiting, capturing screenshots, and generating PDFs, Playwright streamlines the testing process and enhances the reliability of web application performance. Playwright supports multiple programming languages, including JavaScript, TypeScript, Python, C#, and Java, making it accessible to a wide range of developers. Playwright is an open-source automation library developed by Microsoft that is designed for testing web applications across various browsers.

What Does The Software Development Process Entail?

Additionally, certifications and continuous learning can significantly enhance earning potential. Geographic location plays a crucial role in salary variations, with tech hubs like San Francisco, New York, and Seattle offering higher compensation compared to other regions. Lastly, reporting helps us measure the effectiveness of the automation testing process itself. A well-prepared report presents data in a simple and organized way, making it easier for everyone to track the project’s progress and make https://uvik.io/ informed decisions.
It’s essential for a Senior Backend Developer to have a strong understanding of databases, as they play a critical role in shaping the backend architecture and ensuring smooth data management. For implementation, I choose a suitable programming language and framework based on project requirements and team expertise. Once the resources are identified, I define the appropriate HTTP methods (GET, POST, PUT, DELETE) for each resource, ensuring they adhere to REST principles. Through teamwork, effective communication, and continuous improvement, we successfully delivered a robust backend solution that met the project’s requirements and contributed to the overall business goals.” To overcome this, I collaborated closely with the frontend developers, database administrators, and DevOps team to design an architecture that utilized microservices and message queues. The main challenge was ensuring that the system could scale efficiently while maintaining high performance and reliability.
But, they require more overhead due to increased context switching and direct OS involvement. ULTs are managed by user-space programs, not the OS, making them faster to create and manage due to less context switching. Both are vital for maintaining data integrity and system stability in multithreaded environments.
