I applied through a recruiter. I interviewed at Millennium in Mar 2026
Interview
C++ interview covered STL containers, memory management, multithreading, and OOP design patterns. One live coding problem. Interviewer was technical and fair, process moved quickly, clear communication throughout. Questions felt relevant to the actual role rather than generic brain-teasers, and there was room to discuss tradeoffs in my approach rather than just reaching a final answer. Overall a positive, well-organized experience
