I brought an electronic logbook to my Delta interview, and explained to them it was my way of putting my civilian and military time together in one place (there are fundamental differences between the way these two kinds of time are logged). I brought my original paper logbooks from my bug smasher days in case they asked to see it. They did.... and told me they wanted to see original endorsements, sign-offs, and were specifically looking for any "unsat" checkrides.
