I applied online. The process took 2 weeks. I interviewed at Climate Institute (Washington, DC) in Jan 2015
Interview
It manly consisted on a phone call because I was not in DC at the moment. Very casual and very nice, they wanted to know my areas of interest in order to see in what research project they could include me.
Interview questions [1]
