Last round of PhD recruitment next week and I am terrified.

r/

I am on the fifth and final round of recruitment to a PhD position at a large well known research institute in Europe. They are paying for me to fly out and do 2 days of in person interviews.

I just got my schedule yesterday and I have 4 (FOUR) 1-on-1 interviews with various faculty members. I also have 1 on 1s with current lab members 8 in total (although these seem less formal) and a seminar presentation.

To say I am nervous is an understatement. Their are 2 positions available (although I am only interested in 1 of the projects) and 4 candidates invited for this round.

I am particularly worried as the institute is heavily immunology focused but I am not an immunologist. The project that I applied for is not related to immunology but as two of the professors I have 1-on1s with are I am worried they will ask me complex questions that are beyond my field of expertise even though it’s not relevant to the project I am applying for.

Does anyone have any advice? Is it likely that each interview is just going to be more general with only those with the PI focusing on the project it’s self?
