Design and Implement a C++ Telemetry Aggregator With Inheritance
Overview
What this challenge is about.
Design and Implement a C++ Telemetry Aggregator With Inheritance. Intermediate challenge in code. Writing production code that solves real engineering proble...
The Brief
What you'll do, and what you'll demonstrate.
Build a C++ telemetry aggregator using inheritance and polymorphism that supports 6 sensor families with clean, testable abstractions.
This is not a coding exercise. It is the work a software engineer does between a Jira ticket and a merged PR. That distinction matters to every hiring manager who has seen candidates solve LeetCode problems and none who have shipped production code under real constraints.
When you finish, you will have something most graduates do not: a real-world deliverable, verified by Ewance, that you can show to a hiring manager and say "I did this. Here is the proof."
Earning criteria — what you'll demonstrate
- Apply abstract base classes and polymorphism in idiomatic C++
- Use RAII for safe resource lifecycle in a sensor abstraction
- Structure unit tests with fakes for polymorphic interfaces
- Document design choices with UML and rationale
