SDET Coding Round Preparation

Build confidence for SDET coding interviews through hands-on programming questions. Strengthen your understanding of arrays, strings, maps, linked lists, and core logic-building patterns. Learn multiple solution approaches to common interview problems and improve your coding-round readiness. Coding rounds are a critical part of SDET hiring, requiring candidates to demonstrate strong problem-solving ability, clean logic, and practical programming skills. This course helps learners prepare for technical interviews by working through commonly asked coding questions related to strings, arrays, maps, matrices, linked lists, and number-based logic. The course begins with an introduction to the preparation journey before moving into hands-on coding problems. Learners explore matrix transposition, string length calculation without built-in methods, linked list fundamentals, reversing maps, removing duplicate array values, reversing words, counting character cases, finding the second largest number from a string, and calculating word frequencies. As the course progresses, it covers array rotations, mountain array validation, leader elements, unique character extraction, maximum product of triplets, and string encoding and decoding. By following the course flow, learners gradually build the ability to break down problems, identify suitable approaches, and implement efficient solutions. By the end, learners will be better equipped to approach SDET coding interviews with clarity, confidence, and a structured problem-solving mindset. This course is ideal for aspiring SDETs, QA automation engineers, software testers transitioning into automation roles, and technical professionals preparing for coding interviews. It is also useful for developers who want to revise common coding-round questions. The course uses a problem-first approach, explaining each coding challenge through practical implementation. Learners progress from foundational questions to more logic-driven problems across strings, arrays, maps, and linked lists. Each video focuses on clear reasoning, implementation flow, and interview-oriented understanding. This course is based on SDET Coding Round Preparation, by Jatin Shharma.
