There is a useful button on the Shortlist & CVS and Candidate Activity pages of a Job record called Show on Google Maps. When selected it will launch Google Maps and plot locations by showing a pin for the Job (in red) and multiple pins (in blue) for all the Shortlisted Candidates.

When used from the Candidate activity page of a Candidate record it will use pins to show which candidates are closest to the job being recruited for, and how many jobs are local to specific candidates.
