      Neutral experience
      Average interview

      Application

      I interviewed at Luna Innovations

      Interview

      All done remotely, 3 rounds of video calls, with various different people. A very classic, standard interview process with questions about technical ability and soft-skills. Didn't seem to have loads of questions prepared in advance but more asked questions based on what was in my CV

      Software Engineer Interview

      Anonymous Interview Candidate
      Blacksburg, VA

      Neutral experience
      Average interview

      Application

      I applied online. The process took 6 weeks. I interviewed at Luna Innovations (Blacksburg, VA)

      Interview

      Initial communication was good with HR. I had a quick phone screen going over my experience, and was quickly offered a phone screen with the hiring manager. At this point, communication became sparse and I followed up multiple times before being invited for an on-site multi-panel interview. Everyone seemed nice and it seemed to have gone well. The hiring manager told me he'd call next day but I never heard anything, even after following up with HR.
