A straightforward question asking you to outline your strengths and qualities. At least that is the way you should look at it. You should ideally consider the key requirements made of fast stream applicants from the information the selection board provided you with and reflect this back to the board.

Desire/ambition to succeed

Interests in taking a lead role

Willingness to work flexibly and as required

A profound interest in researching and preparing policy documents

An interest in and aptitude for team work

Ability to take decisions

Ability to priorities activities etc,
