Tesla interview questions

Started with an in to to the company through a family friend. Applying online failed, but it finally got my resume to a recruiter who was no help. However, he gave me the name of the university program supervisor. I was contacted about a potential internship from a different university program supervisor. One interview with her over the phone that lead to a follow up with a "mentor". After that an interview with Huibert Mees, Engineering Manager. After that I received an offer.

I originally saw a posting on my university's career development center website from Tesla Motors for intern positions with directions to fill out their Taleo-supported website application and to also submit correspondence to an alum of my university with my resume and cover letter. I did so and received a reply from a University Programs Coordinator approximately three weeks later. She set up an informal "chat" with me as to my interest in Tesla, future goals (long and short term), and my availability for the potential internship. About a week later I received an email from her to set up my first of three interviews of members of the Cell Engineering Team at Tesla. I interviewed with three Tesla employees over the course of three weeks. The first two interviews were very technical and they asked a lot about my knowledge of batteries, specifically lithium ion battery technology, and my research experience with electrochemistry. Each of the first two interviews lasted exactly thirty minutes. The third interview, I spoke with the Director of Battery Technology and the interview was not technical; it was more about my personality and personal affinities for different subject matters in school. The final interview lasted no more than fifteen minutes. Two weeks after the final interview I was contacted by the University Programs Coordinator with an offer of an internship from the Battery Technology team.
