i would like to get info from poles living in uk if there are still jobs to be found. i am doing cad and not thinking of doing manual labor. i searched the net and found that there's a considerable amount of cad job vacancies but don't know if they were true? do they priorities british people over eu?
My only knowledge of the industry you refer to is that CAD stands for "computer aided design", so I can't comment on specifics, however, I think that it would come down to how strong your CV is that will be what counts.
Any foreigner applying for such a job would have to have excellent English skills, both written and verbal, but that would be true of any job that isn't a McJob or shovelling sand on a building site.
I think they would want to know what your long-term plans were and whether or not you intended to stay in the UK. If you didn't plan to settle here, they might be put off hiring you as they might see it as a waste of their time and money.
