Coding interviews are assessments used by tech companies to evaluate a candidate's programming skills and problem-solving abilities. During these interviews, candidates are typically asked to solve coding problems on a whiteboard or through an online platform. The focus is often on algorithms, data structures, and the ability to think critically under pressure. These interviews may also include behavioral questions to assess a candidate's teamwork and communication skills. Companies like Google, Facebook, and Amazon often use coding interviews as part of their hiring process to ensure they select candidates who can effectively contribute to their engineering teams.
