It depends on what you want the EE to do?
Not all electrical engineers have the same training. Just like doctors they usually have a specialty.

If you are interested in plant construction and facility maintenance, I would ask about codes and practices.
If you want production machines to be kept running, then go for troubleshooting techniques and knowledge of related fields (i.e. hydraulics and pnuematics).
If you care about computers and networks then focus on electronics and software.
