Is Sage Software Easy To Learn To Use? ?

i was looking for a job through this staffing agency, and they said this company wanted someone who knows Sage software.
I told them i knew spruce, peoplesoft, and quickbooks. but i really have only used spruce to do some accounts receivables. i have never used peoplesoft or quickbooks. So do you think it’ll be easy for me to pick up sage software? I didn’t find spruce to difficult to use.
Like should i tell them I’m a fast learner and can learn the software quickly.
