Coding Interview Prep & CS Topics Covered

Algorithms, data structures, system design and CS theory — the core topics behind FAANG and technical interviews.

💻 Computer Architecture

CPU pipeline, caching, RISC vs CISC, memory hierarchy, speculative execution, SIMD, Amdahl's law.

🌳 Data Structures

Arrays, linked lists, trees, heaps, hash tables, tries, Bloom filters, skip lists — with Big O analysis.

⚡ Algorithms

Sorting, graph algorithms, dynamic programming, greedy, P vs NP, complexity classes, randomised algorithms.

🗄️ Databases

SQL, normalisation, ACID, CAP theorem, indexing, OLAP vs OLTP, MVCC, NoSQL types.

🤖 AI & Machine Learning

Supervised/unsupervised learning, neural networks, transformers, LLMs, overfitting, evaluation metrics.

🖥️ Operating Systems

Processes, threads, scheduling, virtual memory, deadlock, file systems, concurrency primitives.

Great for technical interview prep

The Linkup game builds the conceptual grouping skills you need for system design. Trivia Royale covers the theoretical foundations behind every algorithm and data structure question on FAANG interviews. NumRush sharpens the mental maths behind Big O reasoning. Just 5 minutes a day keeps CS fundamentals sharp — even when you're deep in a project sprint.
