“In my last project, I developed embedded software for a custom hardware device using C and C++. I faced challenges with memory management and real-time processing, but by optimizing the code and using efficient algorithms, I was able to improve the system's performance significantly.”

2. Can you explain the difference between C and C++? When would you use one over the other?

This question tests your understanding of programming languages and their applications.

How to Answer

Explain the key differences between C and C++, such as object-oriented features in C++ and procedural programming in C. Provide examples of scenarios where one might be preferred over the other.

Example

“C is a procedural programming language, which is great for low-level programming and system-level applications. C++, on the other hand, supports object-oriented programming, making it suitable for larger projects where code reusability and organization are essential. I would choose C for embedded systems with limited resources and C++ for applications requiring complex data structures.”

3. Describe your experience with Linux and the GNU toolchain.

This question assesses your familiarity with the development environment commonly used in embedded systems.

How to Answer

Discuss your experience using Linux for development, including any specific tools or commands you frequently use.
