Fortinet Web Developer interview questions

I spoke to a hiring manager at a job fair, he looked through my resume and asked me some questions about my experiences to get a sense of how "green" I may be. It was very conversational and he really seemed to like me, he said I would definitely hear back from them. He knew I was a new graduate and did not have an opening on his team, but did have a front-end position on another team (not the best fit for my experience) and he mentioned typically they hire more experienced people for those roles. 2-3 days later I received an email from HR to schedule an offline 48hr test and more information about the role. After that i did not hear back from them (not surprising since my solution was only about 70% done, although I enjoyed it and learned a lot while doing it). It would be nice if they sent a declined email rather than nothing at all.
