One round, should be okay if you prepare. Interviewer let me know they typically target high schoolers who are able to swim and are are able to drive to the work site in a quick manner.
I applied in-person. The process took 1 day. I interviewed at Charles River Country Club (Boston, MA) in May 2014
Interview
single interview with few questions, they don't exactly grill the future busboys and I really doubt anyone is actually ever going to read this I just need to do this so I can actually get access to the full site.
