Not trying to be pedantic FFF but 'all the licences and ratings we require for applying for jobs' is not quite correct. One can apply for a 2 crew airline job as co-pilot with merely a CPL. No frozen ATPL is required (ie you could be one of the rare breed who only ever sat CPL exams and never sat the ATPL's), but in reality most airlines want you to have the ATPL exams so that they can put you in the left seat at some point.............
