I don't know Genghis but engineering training does help.
You have more of a feel what the plane is doing and the forces you are playing with.
The technical lingo is more defined.
Problem solving is more logical.
Talking to the spanners you tend to give the required data on the first chat. You give them more info than they require not less and they have to scratch there heads and send the plane out for another flight.
But then again there would an argument that in modern aircraft soft people skills are actually more useful.
