Domain knowledge has to be picked up nonetheless but it's not really an issue.

I would say that the different domains of policy making in our civil service can broadly be split into social (moe, moh, MSF, MCCY, MCi), security (mindef, mha), economic (MTI, MOF, MND, mOT, mewr) and central administration (psd). You may consider specializing in policy work within a 'domain family' eg social or economic.
