      Field Service Technician Interview

      15 July 2025
      Anonymous employee
      Cannon AFB, NM
      Accepted offer
      Positive experience
      Easy interview

      Application

      I applied online. The process took 2 weeks. I interviewed at L3Harris (Cannon AFB, NM) in July 2025

      Interview

      The recruiter reached out to me via email and scheduled an initial Microsoft Teams interview with the program manager, which lasted about 30 minutes or so and consisted mostly of a casual discussion regarding my background and why I was leaving my current employer. The second interview was a technical interview (also via Teams) with the site lead and several techs. It consisted of about 10 to 15 questions regarding electro-optical sensor theory and other related stuff. It wasn't difficult, and I was familiar with the majority of it, but I couldn't immediately recall a few details off the top of my head. The entire process from the recruiter's first contact to receiving an offer letter took only 20 business days. The compensation offered was pretty solid for the local area ($38/hr) and around what I requested. The benefits look great too (9/80 work schedule, unlimited PTO etc), and it sounds like there's a possibility of relocating to several other work sites if you're interested in that.

      Interview questions [1]

      Question 1

      What is emissivity and absorption in relation to midwave IR cameras? Can IR cameras see through windows/glass? What is SWIR (shortwave IR)? What is thermal crossover, and when does it occur? How do digital cameras function? What is the difference between RS-232 and RS-422 serial communication protocols, and how many TX/RX wires do they each have? Where would you go in Windows to find which COM port a USB-to-serial adapter is using? What's the hardest thing you've had to troubleshoot? Why are you the best candidate for this job? What are your future career plans/goals?
