A recruiter from the HR department contacted me for a general screening over the phone. In this screening the recruiter went over my experience briefly and asked for my availability for an actual interview. I was then interviewed by the team that I would be working with over the phone the following week. In this interview they went over the position and asked how my experience related to the job functions. They also asked about my major, career aspirations, why I chose to come back to JPL, etc.
