  • Anduril Industries Software Engineer Interview Experience: automated recruiter messages and three essaysAnduril Industries · Software Engineer · Aug 2026
    Withdrew

    A recruiter contacted me unexpectedly with a message that felt AI-generated, and the exchange felt automated from the start. I tried several times to speak directly and move away from that phrasing, but it kept returning. She eventually sent a specific role tied to my resume that also read as though a bot had generated it, including a supposed office location in my city. After a few more chats, s…

    The process began with a quick recruiter screen that was mostly about logistics and conversation. We covered my background, past work, and interest in the role. Sometimes a small technical question came up. In one screen it was basic cantilever-beam knowledge; in another, there was no technical question at all. The recruiter also asked about fit and expectations, including team matching and motiv…

    No response

    A recruiter contacted me with a message that looked AI-generated. I asked to speak with a real person, but each reply returned to the same automated tone. She eventually gave me a "role" that also felt automated, apparently tailored from my resume and describing a city office I knew Anduril did not have. After more back-and-forth, she said she would put my resume in the system only if I wrote thr…

    Rejected

    This role was billed as fullstack, but the interviews barely touched anything front-end related. And the final round — I got screwed over by the hiring manager. The phone screen was on 4/17. After I finished it we just chatted. The next day HR told me I passed and moved on to the onsite (VO). VO Coding 1 Question 1: a simple calculator that only needs to support addition and subtraction.

  • Anduril Software Engineer interview experience: HackerRank and ghostingAnduril · Software Engineer · Take-home Project · Jul 2026
    No response

    I started with a recruiter conversation that was kind and upbeat. Afterward, I received a HackerRank assignment, completed it, and waited. Then the process went quiet and I was ghosted. The positive recruiting call made the lack of any follow-up after the take-home feel especially abrupt. From what I saw, the broader process usually went from recruiter conversations to an engineering screen and t…
