Gamucatex interview questions

Went into the interview looking forward to a job that ticked all the boxes. Was told we might be able to go through a goverment system to get me paid for my work here. Was contacted by the jobcenter afer the interview saying the no longer want to presue the goverment plan to pay me and want me to work 20 hours for free. Keep seeing even more listings from this company for similar jobs and they always include in a big wall of text in a small section 'unpaid position' wish they were more transprant and just put it in the title instead of tricking people into thinking this could be a dream job or making people think think they have a means to pay them then taking it away,
