Software EngineerL3Medium to Hard

Tekion's Senior Software Engineer (L3) interview process is designed to assess a candidate's technical expertise, problem-solving abilities, system design skills, and cultural fit within the company. The process typically involves multiple rounds, starting with an HR screening, followed by technical interviews focusing on data structures, algorithms, and coding, then a system design round, and finally a managerial or behavioral round. The goal is to identify candidates who can not only write efficient code but also design scalable and robust systems, and collaborate effectively within a team.
