There's a thread on Airline Pilot Central about the interviews.
Some of the the 767 flying is domestic night hub turns for DHL out of CVG. Some is international PAX.
First year guarantee is 50 hours a month at $75.75 for both planes. But there's a rig that pays an hour's pay for every 4.95 hours away from base. So unless you get stuck sitting reserve in base you'll beat guarantee after 10 days. Second year and beyond the guarantee is 62 hours a month so it takes 13 days on the road to better it. Second year -400 is ~90 an hour and the 76 pays 92% of -400 pay.
