I'm an employer, we've hired about 80 people in the past 2 years, mostly through referrals from people already working for us. All my employees know of my passion for beer and homebrewing so applicants will actually mention it pretty often. But there's a connection between geologists and beer that is fundamental, for many years all the homebrewers I'd ever met were geologists, and even today I'd say that over 75% of the homebrewers I know are geologists. For the record I don't actually hang out with geologists very often, not even my employees.
