Three rounds, all behavioral. This was for a non-technical position, however. The overall process was smooth and was conducted over a couple of weeks. They take a while to get back to you if the team you're interviewing for hasn't made a decision.
I applied online. I interviewed at Tesla (San Francisco, CA)
Interview
The interview took a couple weeks, and the decisions were made a couple months later. First couple of interviews were phone calls with the recruiter and hiring manager, then a case study, presentation, followed by a day of panel interviews.

Question 1
Many pricing structure questions, hypothetical scenarios, etc.
I applied online. I interviewed at Tesla (Germany) in Jul 2025
Interview
I applied online via the Tesla careers page and was contacted by recruiting a short time later. First step was an email with some “hard criteria” questions (availability, 6-month full-time internship, enrollment status, start date, etc.). After I replied, I had an online interview.
The interview itself was professional and friendly. We talked about my background in mechanical/electrical design, EV/high-voltage topics, CAD skills, and some basic questions on mechanics, materials, and DFM/DFA. They also asked about how I approach problems, how I work in teams, and why I wanted to join the High Voltage Distribution team.
Technically, I felt the fit was good and the conversation went well. However, in the end I was rejected because my German language skills were not strong enough for what they needed in that team. This was communicated politely, but it’s important to mention: even for an internship, German fluency can be a deciding factor, depending on the team and role.

Question 1
“What CAD tools have you used, and what kind of models/drawings have you created with them?”
“Imagine you need to route a high-voltage wiring harness through a tight area. What would you consider to avoid issues like chafing, bending, thermal or vibration problems?”
