I got a call from the Principal Investigator, who told me I would be contacted by someone for an interview. I was interviewed by a Research Associate and the Program Director. The interview wasn't all that difficult or stressful - it seemed like they wanted me to be at ease. Afterwards, I was introduced to one of the investigators and spoke with him in his office for a little while about work that he might want me to do if I were to work there. I received an email soon after saying I should be hearing from them soon. I did hear from them soon after asking me to come in and meet with the Principal Investigator - I was offered the job then.

They ask you about why specific research lab, what can you bring to Yale and what can the lab bring to you, and they ask questions about your previous research papers.
