A recruiter emailed me and set up an initial Microsoft Teams interview with the program manager. It was about 30 minutes and mainly a chill chat about my background and why I wanted to leave my current job. Next, I had a technical interview, also on Teams, with the site lead and some techs. They asked about 10-15 questions on electro-optical sensor theory and related topics. It wasn't super hard, and I knew most of it, though I blanked on a few details. The whole thing from the first email to getting an offer took only 20 business days. The pay was good for the area ($38/hr), matching what I asked for. The benefits are also nice (9/80 schedule, unlimited PTO), and they mentioned possible relocation to other sites.

The interview process was thorough and time-consuming, taking a significant amount of time. However, communication was good. They require a lot of experience, but they seem like a good group to work with. Be prepared for challenging questions and to demonstrate your knowledge.

After applying online, I was contacted by a recruiter who set up a 30-minute 1:1 phone interview. Following that, the recruiter requested a 45-minute management panel phone interview. Then, I was contacted again by the recruiter for an in-person interview with a panel of three management team members, and later that day, I had an interview with Human Resources. Finally, I received a job offer and a request for a background check and drug test.
