Why has it been decided that applicants cannot apply for more than one competition in the main block of first wave competitions?

These competitions are very different in terms of the nature and level of the work concerned. Competition is likely to be stiff and it is important that candidates select the competition which best matches their profile as well as their career aspirations. As in the past when large competitions have been published simultaneously, it has therefore been decided that candidates may not apply for more than one competition or field. This restriction, which will not apply to competitions outside this block, is also necessary for organisational reasons to ensure the smooth and timely running of the competitions.
