I applied online. The process took 3 months. I interviewed at NIH (Washington, DC) in Mar 2015
Interview
Very long process. They have many people asking questions on the panel. Sometimes it feels like the interview questions are timed.
Also, once u complete the first round of interviews you will be asked to come in for a second round of interviews.
Interview questions [1]
Question 1
