If you are asking about females in Intelligence department then be it IB or ISI, most of the time females prefer desk jobs. however sometimes you are also tasked to keep a tab on fellow officer or other officials, you won't see them working in sensitive areas or sensitive assignments. by desk jobs comes - compiling reports, doing admin related work, or as an analyst.
However if you talk about CSS then this is totally different, it is like whole different work, in CSS you get to choose Service group and then you have to compete for that, the top among the women are PAS ( Pakistan Administrative Services ) , Foreign Service, Auditing and Accounts, Pakistan Customs, Inland Revenue
Why is that though, for the ISI and IB?
