Orthodox C++ (sometimes referred as C+) is minimal subset of C++ that improves C, but avoids all unnecessary things from so called Modern C++. It's exactly opposite of what Modern C++ suppose to be.
This list is provided as a guide for tools engineers of all skill levels looking for jobs in the game industry. It's meant as a guide to topics that should be pursued broadly in order to be well spoken in an interview. I doubt any hiring manager requires deep knowedge across every topic, but an ideal candidate would be somewhat knowledgable (aware of its existence if asked directly) with all topics here.
Each list of bullets increases in difficulty, so later bullets are more applicable to senior (or even director) level candidates.
Good luck.
