Pretty simple. Was done online over Skype. The interview itself was very long and they seemed desperate for more help. The interviewer was very friends and respectful. Was offered the job but didn’t take it for a number of reasons

Painless. Received a call. Scheduled an interview. We met at a coffee shop. He prepared some questions but was unable to access them on his computer. He came up with some standard questions and I talked a bit about what school I'm going to and my interests.

First I received a phone call and had brief phone interview and was asked some person questions. Then we scheduled an in-person interview in which we met at a local coffee shop.
