Questions in interview are totally depends on the Interviewer and his/her domain knowledge in that particular task. So depending on that the technical round will be. If you have the detailed job description of the said designation then you need to know little bit about the particular tasks. If you know any one from the Organization then check with them about what they perform and then try to gather related information.
Typical Data Management related questions may be asked but not limited to like Data Management processes, popular CDMS used in market, guidelines followed by Data Management, data entry types, what is Data validation, what are edit checks and why they are needed, which are medical dictionaries used for coding purpose, Data Management Plan, Annotation of CRF etc...
They will assess the knowledge about technical skills as well as other things like attitude, team player, communication, flexibility, confidence etc.
All the best!
