Volunteering
It's great if you are able to volunteer to help a company or cause.
It is understanderble that people need to make money themselves, and whilst they might like to volunteer, they also need to find ways to make their own money. But the thing with volunteering is that it gives you a great chance to experiance working in a certain field, plus it's somethinfg that you can put on the CV. It's often flexiable too, and may only need a hour or so a week.
