The three steps

How each skill is tested

Questions get harder as you get better at a skill. A step counts once you answer a question at that level well, in an interview or a practice session. Nobody ticks a step off: you show it.

  1. 1

    Fundamentals

    Explain the basics and the key terms in your own words.

  2. 2

    Applied

    Use it on a real task, the way the job does.

  3. 3

    Scenario

    Decide in a realistic situation and explain the trade-offs.

Freshers start at the fundamentals. With 1 to 6 years of experience, questions start at the applied step.

What does a C++ Developer interview cover?

6 of the job's own skills: the core ones, Memory management and RAII and Modern C++: move semantics and templates, then Operating systems, Computer networks, Time and space complexity and Debugging. Every interview also has the HR and behavioral round (Ownership and impact, Teamwork and conflict and Learning and growth).

Which skills should I prepare first for a C++ Developer interview?

Start with the core skills: Memory management and RAII and Modern C++: move semantics and templates. They come up in almost every C++ Developer interview. Then move on to Operating systems, Computer networks, Time and space complexity and Debugging.

What kind of questions are asked in a C++ Developer interview?

The interview types are Mixed, Technical and Behavioral. Each skill is asked at three levels: Fundamentals (explain the basics and the key terms in your own words), Applied (use it on a real task, the way the job does), Scenario (decide in a realistic situation and explain the trade-offs).

Is this C++ Developer roadmap for freshers?

Yes. Freshers start at the fundamentals. With 1 to 6 years of experience, questions start at the applied step.

How do I know I'm ready for a C++ Developer interview?

When the core skills are answered strongly on applied questions, at least half of the job's skills are assessed and none of the key ones is weak. A mock interview measures this for you, skill by skill.

Is it free?

Reading the roadmap is free. Tracking your progress on it needs a free account, and your first mock interview (3 questions) is free, with no card needed.
