Hi everyone. This is my first post here. I have been invited for a phone PhD interview at a London based university.I am not sure what sort of questions they will be asking me. It is a visual analytics PhD and I am totally clueless. Do I have a lot to fear from this interview? Am I also supposed to have the answers for all the scientific questions? I have submitted my proposal but the only way to move forward is to investigate everything. Can someone please guide me?
