Thats a very intelligent question.
The answer, presumably being yes or no is a little harder.
A lot depends on your age and background, common sense and manners are for many (not all) older generation engineers a given but maybe less so for some youngsters (which admitedly we were once).
Also there are some engineers who dont understand that you cant deal with a person in the same way as you can deal with a a broken bit of metal.
I think that a good engineer with good people skills is a asset which a company ignores at its own cost.
