I have been working at NASA full-time (More than a year)
World's leading institute in development of remote sensing instruments. The position directly use NASA remote sensing data, rare anywhere else.
NASA is a multi direction institute and the focus is not on a specific problem but very diverse.
I applied online. I interviewed at NASA.
Application, and then one formal interview. No surprising questions, mostly about my experience, what I want to learn, and how I work in a team. Mostly questions that were about personality.
