Hi all, I am selected for an interview round in one of the universities that I applied to for PhD in Biostatistics, and they wanted to schedule 4 Skype interviews! The kind of questions that one expects in these interviews can be covered by one interview only, so I am really having troubles preparing for 4 of them for the same university. I will be very grateful if someone can share their views or similar experiences, if any. What should I expect? Its somewhat difficult to brush up every relevant topic learned over the last 4 years, isnt it?
