An interviewer will eventually ask about the multiengine airplanes you have flown. They typically ask about systems, limitations, autopilots, and flying experience. It sounds like this AirCam is a ultralight (or nearly so) aircraft with very simple systems (fixed gear, fixed prop, VFR, etc). Flying this airplane may be fun, but in the very competitive employment market, other applicants will have flown 'real' twins. Put yourself in the interviewers shoes, would you be impressed by someone with the majority of their multiengine flying experience gained in an ultralight?
