A few days back I emailed a potential supervisor in one of the Top schools in Computer Science. To my surprise I got an instant reply from him mentioning that I should apply and he has funding for research assistants like me. He also mentioned a few questions about research topics so to follow up I sent him the answer and asked his opinion. However I didn't hear from him after that. Here I would like to mention that questions were not to test me but just general research questions which he is interested in, and my reply was also more like a discussion and asking his opinion. Now I am confused what I can get from this, and also should I ask him somehow to have Skype interview? He is really a great professor and has his own funding so may be he can even effect committee decision.
Thanks.
