C++ Developer Assessment Template

Ready-to-run c++ developer test covering modern c++17/20/23 features, raii & smart pointers, templates & metaprogramming — with structured rubrics, sample questions, and AI-proof integrity baked in. C++ hiring is extremely level-sensitive — strong senior candidates explain modern memory models and move semantics without prompting, while mid-level candidates lean on RAII vocabulary without depth.

Sample questions from this template

A preview of the questions you'll see when you use this template.

Multiple ChoiceEasyQuestion 1

Which of these is the most idiomatic way to handle modern c++17/20/23 features in production?

  • A.Hand-rolled implementation with no library support
  • B.Battle-tested library + thin abstraction
  • C.Copy from the latest blog post
  • D.Avoid the pattern entirely
Multiple ChoiceMediumQuestion 2

A c++ developer reports a regression in raii & smart pointers. Which signal is MOST likely to identify the root cause?

  • A.Application logs at INFO level only
  • B.Recent deploy diff + relevant trace
  • C.Number of open tickets
  • D.Restarting the affected service
CodingMediumQuestion 3

Implement a small module that demonstrates templates & metaprogramming. Include unit tests for happy path and one edge case.

Hint: Prefer clarity over cleverness; tests count.

CodingHardQuestion 4

Refactor the supplied snippet to fix a subtle bug in move semantics & perfect forwarding without changing the public API. Explain the fix in 2–3 sentences.

Hint: Read the tests; they encode the contract.

EssayMediumQuestion 5

In 200–300 words, describe how you'd evaluate a tradeoff between modern c++17/20/23 features and concurrency primitives on a real project.

VideoEasyQuestion 6

Walk us through a recent c++ project where raii & smart pointers was the deciding factor. (90 seconds)

Frequently asked questions

Who is this C++ Developer assessment template for?+

Hiring teams screening c++ developers at senior level. C++ hiring is extremely level-sensitive — strong senior candidates explain modern memory models and move semantics without prompting, while mid-level candidates lean on RAII vocabulary without depth. Use it for inbound applicants, sourced candidates, or as a take-home equivalent before live interviews.

Can I customize the C++ Developer template?+

Yes — and we encourage it. The default C++ template covers the common case; the right move for your team is usually to edit the rubric to match how your hiring committee actually scores.

Does this C++ Developer template include AI cheat detection?+

Integrity detection is on by default for the C++ Developer template. Each signal (paste, biometrics, edit-pattern, focus loss) reports independently so you can override us when context warrants.

Can c++ developers preview sample questions before the timer starts?+

Practice questions, sample data, and a tooling tour all run before the C++ Developer timer starts. Most candidates hit the real questions warmed up rather than cold.

How do I reuse this C++ Developer template across multiple jobs?+

Templates are first-class. You'll typically maintain one or two C++ variants (e.g. mid vs senior) and clone the right one when a new req opens.
