The only Other time that I used for my airline interviews was when I was the PIC. Other time was not included in my Total time, just where applicable for my PIC hours. I included a summary sheet of my hours with my log books including explanations/assumptions used to calculate totals. It must've worked since I received CJOs at both airlines I interviewed with, one of which was my #1.

PIC time is always good, if you're the one who signed for the airplane.
