Each microservice focuses on a specific functionality and can be developed, deployed, and scaled independently from the rest of the system. By explaining the concept and its benefits, you demonstrate your in-depth knowledge and ability to https://uvik.io/ adopt innovative approaches to improve the overall performance and maintainability of the systems you build. Next, I collaborated with my team to develop a detailed plan for refactoring, including setting milestones and allocating resources. For ongoing maintenance, I regularly monitor and analyze query performance using tools like SQL Profiler or EXPLAIN statements.
Above six, candidates drop out. Three to four for mid-level, four to six for senior. Companies that run five-round Python interview loops over four weeks lose candidates to companies that run three rounds over ten days. If your interview script still includes “what’s the difference between print as a statement and print() as a function,” you’re testing for experience that hasn’t been relevant in six years. It also has almost zero predictive value for whether the candidate can build and maintain a production Python service. Our Python developer salary guide covers the 2026 pay bands by level and specialty.
- At my previous job, we faced a significant drop in productivity due to disorganized file management.
- Descriptors govern attribute access by implementing __get__, __set__, and __delete__.
- Create a simple calculator that can perform basic arithmetic operations (addition, subtraction, multiplication and division) on two numbers.
Dynamic typing in Python allows you to determine the type of a variable at runtime, rather than during code compilation. It’s a dynamically typed language with capabilities of garbage collection for better memory performance. It uses English keywords extensively, and has a simpler syntax as compared to multiple other programming languages. Python is a high-level and general-purpose programming language developed by Guido van Rossum in 1991. If you’re starting your career in tech, learning these basic Python interview questions is essential.
Q13. Write a program to find the intersection of two sets.
Ask for side projects (like game development). Do they contribute to any open source software projects? Even college performance, while it helps you to assess formal education, doesn’t give a complete picture. He writes about the world of work.
“Tell me about a time you disagreed with a technical decision on your team.” The wrong answer is “I’ve never disagreed.” Nobody believes it. The interviewer is watching how the candidate decomposes the problem, whether they write tests first or code first, how they handle edge cases (what if a value is a list? what about None?), and whether they can explain their choices while they work. Tests recursion, string manipulation, and dictionary handling. Technical screens filter out maybe 40% of candidates. ” has no default answer because Flask doesn’t ship with one.
