Public Works Department (PWD), Govt. of Rajasthan had recently issued recruitment notification 2012 for a total of 586 Junior Engineers (JE) - 568 JE (Civil) & 18 JE (Electrical) in its official recruitment website. Online submission of form has started from 23rd May, 2012 and the last date for online registration is 22nd June, 2012. Written test for selection of these positions would be held on 1st July, 2012.
It is not necessary to be from Rajasthan to apply for this recruitment - even persons from outside can also apply. But however, if your bonafied/home state is not Rajasthan, than you will be treated as GENERAL category candidate, irrespective of whether you belong to any reserved categories. Also, Part-A of Rajasthan PWD JE exam (consisting of 20 marks) contains questions on knowledge of Rajasthan- Polity/Geography etc. So you have to prepare for the same.
