Requirements of ESA WRAG

Hi, been looking on the site re what is required by some one on ESA WRAG, and getting a bit confused. I know you have to attend work related interviews but do you actually have to apply for jobs and take part in work experience. surely the whole point of esa is that you're not able to work at the moment.

Is there an offical link I can look at on this, there seems to be lot of different views. Or maybe that because to rules are changng.

thanks
