Most C++ home assignments aren’t really about writing code. They’re about how you think, structure a solution, and communicate trade-offs. This article explains what interviewers actually look for — and how to approach take-home tasks like a real engineer, not a LeetCode machine.

Precompiled headers are a powerful way to reduce compilation time in C++ projects. The best part is that modern CMake supports them out of the box. In this article, I’ll show you how to set up your CMake project to take advantage of precompiled headers.

Practical techniques: forward declarations, moving implementations to cpp, and PIMPL — explained with real examples. One major factor that can slow down compilation is headers. When they are too heavy or included in every translation unit, they can significantly increase compilation time.

If your C++ project takes minutes to compile, guessing won’t help. Learn how to measure real compile-time costs, analyze JSON reports, and find the most expensive headers and templates using the right tools.
