I applied online. The process took 3 days. I interviewed at Oak Ridge National Laboratory in Apr 2011
Interview
Provided transportation, room and car which was very nice, very interesting culture there and unlike any other research groups I have ever seen. Location could use some work! Involved being interviewed by 6 or 7 separate people throughout the day which was pretty intense and security is taken very seriously.
Interview questions [1]
Question 1
Describe a bug in your code that you solved and how you found and solved it.
