I applied online. The process took 2 weeks. I interviewed at Brookhaven National Laboratory (Brookhaven, NY) in Jun 2013
Interview
I just spoke with the head research directly to ask if I could work with him over the summer and if he had any grant money left to fund an intern. He said he would love to, and we chatted for a few weeks over he phone to see if I was fit.
Interview questions [1]
Question 1
Mostly behavioral questions, and why you wanted to work as a research intern.
