BD Microfluidic Engineer interview questions

two rounds of interview. 1st round: basic questions about your research experience; by the hr in the specific team and last about 30 min; 2nd round: by the director of that division to pick one from the top 3 candidates. did not ask too many questions. I guess because the interview was scheduled to Friday afternoon. next time schedule as early as possible. and basic research interview; 2nd round was by the director.
