36: Recruiter, React and a dancing falcon-wing door

Report date: November 30, 2024 · Role: Software Engineer Intern · Location: Palo Alto · Result: Accepted offer

1. The process began with a recruiter call.
2. The first technical round focused on React.
3. The final round was system design and asked the candidate to design the movement sequence for Model X falcon-wing doors performing a “dance.”
4. The whole process took roughly two to three weeks, with fast feedback between rounds.

37: Scenario design and HITL/SITL depth

Report date: August 6, 2024 · Role: Software Engineer Intern · Location: San Francisco · Result: No offer

1. The first technical interview used fair, scenario-based system questions.
2. The interviewer repeatedly asked for more detail and justification rather than accepting surface answers.
