Software EngineerSenior SWEHard

The Senior Software Engineer interview at Dataminr is a comprehensive process designed to assess a candidate's technical expertise, problem-solving abilities, system design skills, and cultural fit. The process typically involves multiple rounds, including technical interviews, a system design interview, and a behavioral/managerial interview. We look for candidates who can not only write clean, efficient code but also design scalable and robust systems, collaborate effectively, and contribute to Dataminr's mission of providing real-time event detection and response.
