  • A 15-Minute AI Recruiter Screen at 1.5x SpeedTesla · Software Engineer · HR Screen · Sep 2026

    Recruiter round — they sent me an AI link, about 15 minutes. Going in, it was an AI with a really fast speaking speed, roughly like watching a normal video at 1.5x. This position wasn't really a match for my direction, so I answered kind of randomly. This position requires using Go, Java, Spark, Elasticsearch to build distributed systems — talk about your project experience with these How do you…

  • Seven-Hour Palo Alto Onsite, Failed at a Last-Minute HM RoundTesla · Software Engineer · Senior+ · Onsite · Sep 2026
    Rejected

    A few months ago an HR person from Tesla reached out to me about a senior SDE role on an infra team under Tesla AI. I originally didn't have much interest in Tesla, but HR said their package could go up to twice my current package, which instantly got my attention, so I went and did the whole loop. Tesla hires by team, so the interview process and content are entirely decided by the team. It star…

  • Supercharger System Design Where I Never Got Past the First RequirementTesla · Software Engineer · Technical Screen · Sep 2026

    I was asked to design a supercharger with 3 requirements: FR1: Billing / amount of energy delivered (stored in the backend) FR2: Health metrics/telemetry from the supercharger stall (long-term data store) FR3: Screen/in-car application: touch the map, nearest available supercharger (price) I tried to follow the script and design an HLD per FR as quickly as possible, but the interviewer wanted to…

  • Live NumPy Coding on 3D Plane FittingTesla · Software Engineer · Technical Screen · Jul 2026

    Second round for the sensing engineer position. The interviewer had me write everything in numpy the whole time. I hadn't prepared for that at all and couldn't really write it, and after 10 minutes I already didn't want to keep going with the interview, but the interviewer kept pulling me along and dragged it out for the full time anyway. First question: given a list of 3D points and a plane repr…

  • Software Engineer interview at Tesla: gasket toleranceTesla · Software Engineer · Take-home Project · Jul 2026

    Before the interview, I completed and submitted a take-home test. The interview then opened with a problem that sounded simple, involving a gasket and an L bracket compressing that gasket. The interviewer treated it as straightforward, but I overthought the calculation and missed the correct tolerance limit. The subject itself was not complicated. The precision of the calculation was what mattere…
