EY technical round-2 CA articleship

Today I have my second technical round in EY. Apparantly, usually there is only one HR round, one technical round and a partner round. I am done with the HR round, technical round and the HR has scheduled another technical round and this will be conducted by a CA with 10 years of work experience.what does this mean. What are the concepts that i should be ready with. Will there be a partner/director round after this
