Draft Line Cleaning Technician Job

Looking for some feedback for a job I just applied to. Any draft technicians out there want to share their general work experiences? I will also value your experience on the other side of things as a bar owner/worker. For bonus points any experience with Hupp Draft Services?

I'm very excited about this potential job. I know its not a glorious job, but Im not afraid to get my "hands dirty". Plus its a way to get into the beer industry!!
