A coding interview is a job interview format used by tech companies to assess a candidate's programming skills, problem-solving ability, and algorithmic thinking. Candidates are typically asked to solve coding challenges or answer technical questions during these interviews.
Coding interview questions can cover a range of topics, including data structures, algorithms, problem-solving, and sometimes system design. Questions may involve writing code on a whiteboard, solving puzzles, or discussing algorithmic approaches.
Preparation involves practicing coding problems, understanding common algorithms and data structures, and gaining familiarity with the language used in the interview. Candidates often use resources like coding platforms, books, and mock interviews to hone their skills.
Commonly tested data structures include arrays, linked lists, trees, hash tables, and graphs. Algorithms may involve searching, sorting, dynamic programming, and graph traversal. Understanding time and space complexity is also crucial.
Problem-solving is essential in coding interviews, but optimizing code for efficiency is equally important. Interviewers often look for candidates who not only solve problems correctly but also demonstrate an understanding of algorithmic efficiency and can write clean, maintainable code.
