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.

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.
