Each language opens a connected map built from the existing interview question bank. Your answers decide which concepts unlock next.
Foundations of systems programming: pointers, memory allocation, bit operations, and compiler mechanisms.
High-performance OOP: generic templates, virtual tables, STL internals, and memory model.
Cloud-native and high concurrency: Nil Channel suspension, defer evaluation, and GMP scheduling.
Distributed architecture column: JVM memory areas, class loading, and concurrent locks.
Web and fullstack core: prototype chains, closures, and event loop microtask execution.
AI and scientific computing: reference counting, mutable defaults, and integer interning.
