Very coorporative and informal. They ask about basic terminologies and our background. We should be confident enough to attend the interview and must try to answer all the questions correctly or else if any of the question is there which you not have idea then say as it is

The interview was overall good. It consists of two rounds, Aptitude and technical rounds. aptitude round consists of basic english set questions and science related topics. the technical round was about 30 minutes and basically asks job post related questions such as PV and phases of clinical trials
