I applied through an employee referral. The process took 2 weeks. I interviewed at Rafael in Apr 2014
Interview
Interview at Rafael site, meeting with two members of the team I was applying for. Tough interview, need to study hard next time. Study first and second year material and you should be fine.
Met with three engineers, asked several technical questions about some courses I learned. The questions were high level and too complex for my knowledge (I just finished my first semester)
