Here is what you need to do if you decided that this is a position for you. - Have a portfolio of your work. Relevance to the work is most important. Go to video.fortinet.com to get an idea of the type of work. - Have work using AfterEffects explaining some technical process. E.g. google VPN and make a voiced animation how it works. This is mostly what you will be doing here. And the screencaps -Understand basics of networking. -Explain the process you follow for video production. No camera work is involved. It is purely screen capping and animating the conceptual explanation. -Talk about working on tight deadlines (there is very little planning and it is frustrating) -Talk how you would run a project: things are dumped on you and you have to figure it out, both technically and creatively. Often you have to combine several people's input. And make all happy.
