As someone who has done interviews, all I can say is this:

1) If you have EFIS experience with a CFI background, put it down. Those of us (like me) who's only experience with GA EFIS is reading flying or sport pilot, but fly EFIS know what questions to ask.

2) If you put ANYTHING on your resume, be prepared to answer questions on it. Nothing like someone telling me how this or that works, and they don't know that I know alot about it, and they're wrong.
