My thesis professor told me that one of his former students was reaching out for potential interviewees. After announcing my interest and his recommendation, I was contacted for a series of in-person interviews at a hotel in NYC. I prepared using this site so I highly recommend you do that same to get a feel for the questions that are asked. The first day I had one interview. It consisted of introducing myself, discussing my resume, and writing a little bit of code. I was then asked to come back the next day for 3 more interviews which were more technical.
