I applied myself, and was contacted within 2 days by the professor that was running the research about the dates when I could come for an interview - about a week later. I came in and was interviewed by the same professor - 1 on 1. The interview was done in a very casual manner, there were no highly technical trick questions, but we covered a good bit of scientific terms, ideas, and related technology at a fairly high, but very personal level. He was looking for someone devoted to the field and willing to do it solely for your own interest - the same way that he was doing it himself. He let me know that they would not be able to pay me much. Two weeks later I was told that I was an impressive candidate, but they went with another candidate who worked on exact same type of data/research as they were doing.
