Got an e-mail from the HR department and then I after a week went to interview. Three people were present at the moment which was not previously told via e-mail. It was a bit of shock as I thought the interview was going to be one on one.

Easy going related to the field of research. HR interviewer asked common HR questions, why you? What are your strengths and weakness? The main person I was going to work with was nice and accommodating.
