Hello,

As per the official sources, IIIT Hyderabad never discloses how many students were selected for the UGEE interviews. It was not disclosed in 2018 and wasn't either in 2019. Generally, people make intelligent guesses but they are prone to get wrong. Thus I would refrain from guessing and telling you any number but rest assured if your interview is good, you would be getting the selection mail. 

All the best
