Sage Senior Software Engineer interview questions

This was for lockstep.io product/entity. There were 3 rounds in total. First 2 with engineering manager covering system design, which were chill and last with a junior engineer with no specific pattern. That last round interviewer seemed inexperienced and unprofessional. He seemed disinterested from the very start and the feedback I received from recruiter was proof that he had already made up his mind even before the interview began since he reported incorrect details about my work experience and problem solving performance.
