it took five hours plus the one hour check ride
That sounds about right, .. If someone is familiar with
constant speed props, cowl flaps, retractable gear etc from
flying something like a Mooney or Bonanza or Comanche,
then grabbing two throttles intead of one should not pose
much of a challenge.
If someone is not familiar with any of the gizmos and gadgets,
well, now is when you're going to learn about them. They
really don't have anything to do with multi-engine flying, though.
Multi-engine training to me is pretty much learning what
happens (and what to do) when an engine fails. I wrote
this as ground school for multi-training a while back:

Did three hours in a Cessna 310 F and two hours in an Apache.
That's a little weird. You probably could have done it faster
if you had stuck to one type (eg Apache - god I hated pumping
up the gear when that left engine failed) but you probably
learned more by flying two types.
The 300/400 series Cessnas IMHO are "real" airplanes - they
aren't (4 cyl) trainers like the twin comanche, apache, seminole
or duchess.
In addition to the additional power of the bigger 6 cyl engines,
the 300/400 series Cessnas have a far less forgiving wing than
the Apache/Aztec which is a good lesson for a new multi-engine
pilot to learn. After he learns it, of course, install VG's
