Everything" philosophy. You should be more comfortable in perf, or your own custom profiler than in your IDE. TDD is a given. Qualifications: Education: A Bachelor's degree in Computer Science or equivalent proof that you have achieved enlightenment through the study of algorithms. C++ Mastery: You must be fluent in C++. You can explain SFINAE, the Rule of … Zero, and why volatile doesn't solve threading problems. You find memory leaks for fun. CS Fundamentals: A deep, intuitive understanding of data structures, OS internals, and computer architecture. You know why a pointer-chasing linked list is a crime against CPU caches. Performance Tuning: Solid, practical experience making slow code fast. Networking Knowledge: Familiarity with network programming, low More ❯
