    Essential Interview Questions for C++ Developer

    How do you handle memory management in C++ to prevent memory leaks, especially when working on complex systems in Switzerland where reliability is critical?

    In C++, I use smart pointers (unique_ptr, shared_ptr, weak_ptr) to automate memory management and avoid manual memory deallocation. I am also proficient in using memory leak detection tools like Valgrind, especially important in demanding Swiss environments, to identify and fix leaks during development.

    Describe your experience with C++ standard library containers and algorithms. Which containers do you prefer in which scenarios, and why, within the context of developing high performance applications in Switzerland?

    I have extensive experience using various C++ standard library containers such as std::vector, std::list, std::map, and std::unordered_map. I choose containers based on performance needs; for instance, I use std::vector for contiguous storage and fast access, and std::unordered_map for quick lookups. I am also experienced in using standard algorithms like std::sort, std::transform, and std::find to efficiently manipulate data.

    How familiar are you with different C++ standards (e.g., C++11, C++14, C++17, C++20), and how do you leverage the newer features in your projects to improve efficiency and maintainability, aligning with modern development practices in Switzerland?

    I am familiar with C++11, C++14, C++17 and C++20. I leverage features such as lambda expressions, range based for loops, and auto type deduction. These features make code more concise. I utilize move semantics and perfect forwarding for performance optimisation.

    Explain your approach to writing unit tests in C++ using frameworks like Google Test or Catch2. How do you ensure comprehensive test coverage, particularly for critical components used in Swiss financial or engineering systems where precision is paramount?

    I utilize Google Test and Catch2 for writing unit tests in C++. My approach involves writing tests before implementing the actual functionality (Test Driven Development) . I aim to achieve high test coverage by testing all possible execution paths and edge cases. This methodology is very suitable for developing robust and precise systems required in Swiss industries.

    How do you approach debugging complex C++ applications, and what tools or techniques do you find most effective for identifying and resolving issues in a timely manner, especially when working under pressure in a fast paced Swiss environment?

    When debugging C++ applications, I start by using debugging tools, such as GDB. I use logging extensively to track the flow of execution and variable states. I am also proficient in using static analysis tools. When facing complex issues, I apply divide and conquer to isolate and identify the root cause.

    Describe a challenging C++ project you worked on, and explain how you overcame technical obstacles, particularly in the context of specific Swiss industry requirements or standards.

    In a project involving high frequency trading, I was challenged with optimizing code performance to meet strict latency requirements. I utilized profiling tools to identify hotspots and optimized critical sections by using lock free data structures and memory pool allocation. I ensured the system complied with Swiss financial regulations by integrating necessary audit trails and compliance checks.
