I got my interview about a week after applying. The interview lasted about a couple hours, beginning with a written test and then a face-to-face interview with two of the lab's researchers. The test was simple for anyone with a science lab background, and they said that it was more for determining the amount of training needed than to actually decide on an offer. The interviewers were very friendly, and asked straightforward questions about my prior experience and what I'm looking to gain from working there. They also answered all of my questions and even gave me a tour of the lab. I received my offer in less than a week after the interview.
