Technical Coding System Design

I applied through the Tesla careers website and then got invited to two interview rounds. Both were technical interviews. The first one was a typical tech interview, where they first asked about my resume for the first half and then gave me a LeetCode-style question. The second interview was more focused on system design. It started with a simple coding problem, and after I finished, they asked how I could improve the code.

Recruiter reached out to me with some questions for the team. I answered them and sent them back within an hour, and then they took 2 weeks to respond just to reject me... I asked around on discord and found 2 other people who got rejected for the role after getting the same email. What company rejects candidates that often just off a screening email? At least have the decency to get back to me fast, and not waste my time for 2 weeks straight while I’m preparing for the interview.

Confirmed questions1 question
  • What is your expected graduation date? Can you work full-time (40 hours/week)? This one is required. What is the earliest date you can start? Until what date would you be available to work? (our internships need at least 12 weeks) Can you intern for two or more seasons in a row (like Summer 2026 - Fall 2026)? Can you work on-site in Palo Alto, CA? This one is required. Do you have any upcoming deadlines or other offers we should know about? Have you applied for or interviewed for a Tesla internship before, and if yes, which team or recruiter was it with? What’s a good phone number to reach you at? (if it’s international please say so) Will you need immigration sponsorship now or in the future? What is your availability in Pacific time for the next 2 weeks for a possible interview? Please list all dates and times for the next 2 weeks so we can match it with the team’s schedule.

Behavioral Technical Coding Presentation

Started with a few recruiter calls and interview rounds with the hiring manager. Discussed my projects and the team and everything seemed to go well. For the onsite, they ask for a 30 minute presentation on a topic of your choice. During the onsite, it is very clear that it is a very in-group environment where they like to hire people similar to themselves. The coding and questions were not super hard, but it was obvious they want to work with like-minded people. It is their choice, but this ends up wasting everyones time. I didn’t believe the bad reputation of Tesla, but I ended up being proven wrong.
