I applied for phd position in sweeden and passed the screening phase. i was told to do interview via skype and i did twice (both time i was told that i passed the interview). the first was self introduction and the second was about the research topics and environment. now im asked to have an interview for the third time. do you have any idea what it is all about and what it is going to be like.... i would appreciate any kind of advice, tips and previous experiences.
