Recruiter call (remote): Introduction to my background, the role, and the company’s culture. The recruiter explained the upcoming steps in a clear and transparent way. Coding interview (remote, 1h): Two easy/medium challenges on CoderPad, similar to LeetCode or HackerRank problems. The focus was on problem-solving approach, code structure, and explaining the thought process. System design interview (remote, 1h): Scenario-based discussion using Excalidraw to design the architecture of a secure system. Evaluation covered system components, trust boundaries, security controls. Clear communication was as important as technical knowledge. Next steps (planned but not reached): The process normally continues with two additional on-site interviews at Datadog offices. Overall impression: The process was challenging but fair, well-structured, and professional. The recruiter support was excellent and made the overall experience positive.

Manager's interview was unbelievable. The guy was impolite : holding face, bored, not reactive, not asking questions or leading the conversation. Might be a technique but that still would be a shame
