      Difficult interview

      Application

      I applied through a recruiter. I interviewed at IonQ (College Park, MD) in Sep 2024

      Interview

      An initial interview with the recruiter, followed by a take-home test and an in-depth interview with a senior engineer. All went smoothly. Had a few follow-up meetings with the recruiter. Some concerns about potential non-competes were raised, then ghosted.
