This auto flight discussion should really be for another thread. This thread is for guys that want to get hired at Atlas.
As for the question about EFIS quals on the PAQ, there has been (to my knowledge) no guidance from HR regarding the definition of EFIS on the app.
Whatever you decide to do, simply being able to clarify your "EFIS" experience and explain the functionality of that system clearly should help if it comes up in the interview.
My "EFIS" experience was in a SF-340B. Probably not even as sophisticated as your plane. I included it, it never came up during the interview, and I was hired. YMMV.
