In plain English

This repository is a Korean-language study guide for people preparing for their first technical interviews as software developers. The author put it together while preparing for their own interviews, then turned it into a public reference so other newcomers could use it as a roadmap. The README is essentially a long table of contents that links out to many subfolders, each one holding notes on a specific topic. There is also a section collecting interview questions that contributors have actually been asked, and a "reverse interview" section with useful questions a candidate can ask the company. The material is split into three parts. Part 1 covers computer-science fundamentals: general development knowledge (good code, object-oriented programming, RESTful APIs, TDD, functional programming, MVC, Git and GitHub), data structures (arrays, linked lists, stacks and queues, several kinds of trees, hash tables, graphs), networking (HTTP versus HTTPS, TCP versus UDP, the three-way handshake), operating systems (processes and threads, schedulers, memory management, virtual memory), databases (indexes, normalization, transactions, NoSQL and the CAP theorem), design patterns, and algorithms. Part 2 covers programming languages: Java (JVM, garbage collection, collections, generics, threading), JavaScript (event loop, hoisting, closures, Promises), and Python (generators, the GIL, duck typing). Part 3 covers field-specific topics including front-end web development, iOS, and machine learning. You would use this repository as a structured study list while preparing for a junior developer interview. The full README is longer than what was provided.
