I saw an advert for a PhD at UCL, it didn't really have much information so I e-mailed the supervisor with my CV and asking for some more details. He then phoned me and suggested I go to his lab to meet the other students, have a look around etc. So, is this an interview?! I don't really know what to expect. Have been doing the normal literature searches on his name and lab etc but is there anything else I should be doing? Any tips for PhD interviews in general? Thanks for all the help!
