Important to know the history of the club. That'll make it a easy interview for you. The more you know about the club and what it represents, the more likely you'll get a job offer.
I interviewed at Baltusrol GC (Springfield, NJ) in Apr 2014
Interview
I went to the clubhouse and asked if I could meet with the caddy master. My brother had worked there before and he asked how my brother was doing and I said well. They made it seem clear that if I worked hard I would have an easy time working there.
