Fortinet interview questions

I applied at Fortinet through an on-campus career fair for a job as a new grad and went to an on campus screening interview a couple days later. The screening interview was extremely disorganized. I waited for an hour past my scheduled time and there was still a candidate in front of me before I left without getting my interview. Nonetheless, I was contacted a week later by a recruiter saying I was still a potential candidate for a position as a developer and I would need to complete a skill testing question in order to continue. Why not? The position sounded interesting so I agreed and they sent me the "Skill testing question". Only it wasn't just a small test question I have come to expect from my previous interview. It was a fully spec'd out complex end-to-end application that involved everything from building a web client to a back end data store. They gave me 24 hours. The worst part is that there was absolutely no indication that this was even a test problem. The spec showed an application that would be directly relevant to the work being done at Fortinet. I'm pretty sure that I would be spending my day working on a live project, for free, just for the chance to get an interview. Even the filename for the spec is suspicious "Devops_Engineer_Project.txt". Overall this was a terrible interview experience and I would not recommend Fortinet to anybody based on my experience.
