      Software Engineer Interview

      6 June 2025
      Anonymous interview candidate
      No offer
      Negative experience
      Average interview

      Application

      I applied through a recruiter. The process took 3 weeks. I interviewed at Halcyon in Apr 2025

      Interview

      I spoke with two leaders in two separate interviews, under 1 hour each. Then, I had technical interview, focused on Windows kernel and technical experience, with two folks in product management level. The second leader must be a comedian. He explained that the company strives to avoid hiring jerks. After my third interview, the company and recruiter ghosted me. This is pretty funny, but not worth 3+ hours of time to get to the punchline that they do hire jerks, apparently.

      Interview questions [1]

      Question 1

      They asked about various Windows internals concepts: IRQLs, dispatch tables, filter drivers, mutex vs spinlock, etc.
