Very pleasant experience. Met some employees at an information session and arranged an interview on campus. The interview was asking technical questions almost exclusively. The interviewer was quite nice and easy to talk to. I was subsequently brought to Pasadena for an interview at JPL. It was a full-day of interviews, some of which were technical, some of which were conversational and trying to give me an honest impression of working there. Everyone I spoke with was very nice, easy to talk to, and helpful with any questions I had.
