Deloitte Summer Internship interview questions

I applied online and within 2 days I received an email for an interview. The interview went well, the lady was quite pleasant but the way she spoke at the end of the interview, I knew it seems at though they had a candidate already.

online group assessment with the case disconline. self introduction first and 20min case video. then personal presentation for 1. 5min and group discussion for 25min with no presentation. overall 80min
