Real, anonymous reports from people who interviewed for Software Engineer at Fortinet, newest first and distilled into what to expect across the loop.
After I got referred, I heard back from HR and the process quickly became very structured. I went through an online assessment first, then five separate technical rounds, and finally an HR round.

I started with a recruiter call to cover general background details, and then the process moved to a 75-minute online test. After that, I went into a face-to-face interview. The role itself was hybrid, so I had the expectation of going into the office about two times a week.
