First the recruiter gave me a tour of the company. Showed me the place where the spacecrafts were built. Then I was taken into a small room. There a total of about 5 engineers took turns to come interview me individually. Each one had about an 1 hour window. Eventually the head of the team showed up and interviewed me. He explained to me what I got wrong on the exam, given prior to coming in for the interview. Apparently I wasn't good enough though as I didn't get the job.
