I applied through college or university. The process took 2 weeks. I interviewed at Tesla (Fremont, CA) in Nov 2014
Interview
Had one onsite interview with 3 engineers. Was asked about my resume and several math problems/brain teasers. Was given a task to do over the weekend and sent it in. After submitting my response, I got an email from a recruiter saying that they wanted to hire me and was extended an offer. This process took about two weeks total.
Interview questions [1]
Question 1
Was sent a set of data and told to analyze and come to any conclusion. No guidelines on what to look for or what the data was from.
I applied through an employee referral. The process took 2 weeks. I interviewed at Tesla (Seattle, WA) in Mar 2015
Interview
Asked about prior projects and why i choose Tesla. Also some technical questions about programming and electrical engineering.
I have worked there in the past, so my second application was very much accelerated.
Very dependent on the interviewer as well. My first interview was MUCH more technical and by the book. This one was more about me and my history as an engineer.
I applied online. The process took 1 week. I interviewed at Tesla in Aug 2015
Interview
First interview was fairly straightforward. I talked with a university recruiter on the phone. Talked about experiences on your resume and your work ethic. Emphasized hands-on experience. We discussed the work culture and what is expected of Tesla interns. Afterwards, she asked about what interested me the most so she can fit me into a group. She contacted one of her partners to find a best fit for me and that is where I am at right now. Will post an update as the process goes along.
