What programming language interview questions should you prepare for?

1 Know the basics

The first step to prepare for programming language interview questions is to review the basics of the languages you are most familiar with or use frequently. You should be able to explain the syntax, data types, operators, control structures, functions, and common libraries of the languages you claim to know. You should also be aware of the strengths and weaknesses of each language, and how they compare to other languages in terms of performance, readability, scalability, and compatibility.

2 Practice coding

The second step to prepare for programming language interview questions is to practice coding in the languages you are expected to use. You can use online platforms, books, or courses to find coding challenges, exercises, or projects that cover various topics and difficulty levels. You should practice writing clean, efficient, and error-free code that follows the best practices and conventions of the language. You should also practice debugging, testing, and documenting your code, and using appropriate tools and frameworks.

3 Learn new features

The third step to prepare for programming language interview questions is to learn new features or updates of the languages you are interested in or need to use. Programming languages are constantly evolving and adding new functionalities, syntax, or libraries that can make your code more powerful, concise, or elegant. You should keep up with the latest trends and developments of the languages you use or want to learn, and be able to explain how they work and when to use them.

4 Understand concepts

The fourth step to prepare for programming language interview questions is to understand the underlying concepts and principles of programming. You should be able to demonstrate your knowledge of programming paradigms, such as object-oriented, functional, or procedural programming, and how they apply to different languages. You should also be able to explain concepts such as inheritance, polymorphism, abstraction, encapsulation, recursion, concurrency, or exception handling, and how they are implemented or supported by different languages.

6 Be curious

The sixth and final step to prepare for programming language interview questions is to be curious and enthusiastic about learning new languages or improving your existing skills. You should show your passion and interest for programming by asking questions, sharing your experiences, or exploring new topics or technologies. You should also be open-minded and flexible to adapt to different languages, environments, or requirements, and to learn from feedback or criticism.
