DS worked for free, in a small company that needed but couldn't afford extra staff. He knew it was illegal to do an unpaid internship but it exactly fitted the skills he wanted to learn. He did two or three days a week and because the company was small, he really did learn useful skills - the bespoke software for that industry, how to do stocktaking and quality control. After a year and a half of free work he got his first job on a fixed term contract and six months later, his first permanent grad job. Also, the staff he met there moved on to second jobs and so he had a network of people in the industry keeping an eye out for him.
If she knows what interests her, suggest she looks for small companies or start ups that appeal to her and approaches them with a really honest letter, saying: I am seeking entry level work in [this industry - whatever it is] and happy to intern unpaid for a minimum of six months, two or three days a week, in exchange for industry experience. My strengths are XYZ. If you could use this help while you grow your company, I am keen and can start immediately. Please get in touch.
In addition, I strongly advise her to set up a start up of her own, however small. DS started by selling specialist items in the industry he wanted to get into. He went to trade shows and fairs and bought up showroom stock very cheaply and sold it on at quite a big profit, then reivested in more stock. Soon he was being invited to the trade shows as they knew him to be a reliable buyer. It was not a living or a full time job, but it meant he got to know various people in the industry that interested him.
She could team up with a coder if she isn't a coder and design an app. Or start up a shop online selling specific items in demand related to her chosen field. These things might not go anywhere or make much money, but they add to her CV and show her as a self-starter. And she'd learn some skills: website building, how to generate SEO etc.
It is so hard to keep spirits up. What does she love doing? What are her passions? When is she happiest? Help her come up with some ideas based on these and set small, achievable targets.
