Pros: free lunch, make your own hours, friendly enviornment
Cons: not the greatest pay, but better than what r.a. are supposed to make.
Working under one of the professors at the university was a great opportunity for any undergraduate student. He was the Chair of the Canada Research Foundation, which offered a lot of perks to the job in terms of higher pay, and more conferences. Job mainly relied on data entry and analysis. I was also heading the H.R. for the study.
