Tesla interview questions

There was a phone interview where the interviewer asked what I knew about the company, the history, the locations of the facilities. He then asked me what I thought made me a good fit for Tesla. After the phone interview there was an engineering test that was taken online, the test was very difficult and had about 30 questions on it. The questions were mechanical engineering based and included questions regarding damping systems, material stresses, moments, reaction forces, ect.

The process started with 2 brief phone interviews with Human Resources. These interviews included a review of my resume and a discussion about what type of position I am looking for. A series of phone interviews at the Engineering Director level followed. These interviews were also focused on my work history and ability to solve challenging problems. Finally, I was invited to travel to the company's HQ for a very brief (40 minute) panel interview with 4 team members including peers and group leaders as well as a short phone interview with a leader at the VP level. This entire process was drawn out over the span of 3-4 months and it still ongoing.....
