It may be harsh, but for someone who sounds like they are looking to hire minimal people, a student is always a risk. Sure, they can be the best hires you can get (as they can be cheap and uber enthusiastic), but you have to remember, they are students first and your employee second. If they have a uni and a work project due at the same time, chances are, uni comes first.
Don’t get me wrong, I was the working student too and this kind of role for a student would be a godsend…its jsut a be careful about who you hire. I know there were a lot of people in my year that wouldn’t have put heart and soul into a work project.
