For people interested in the sort of questions that were asked this year. Here are some:

Current Affairs
Need for Karachi operation? Why Rangers not engaged in Punjab?
Agricultural problems of Pakistan? Suggest reforms? Kissan Package?
Population control is not a priority of government. Discuss
Urbanization cons? Do you agree with Punjab's development model? Alternate models do not work in a country like ours. You agree or disagree?
Why census not taking place? Indian model?
CPEC is becoming controversial? Why? Its social and political impacts?
Suggest final solution for Syria?
US elections. Policies of Trump?
Rise of IS and its impact on Europe. Blowback on muslims?
Tax reforms? The frequent issuance of bonds will bankrupt us in the near future. Discuss

Islamiyat
Name the Ashra Mubashra
Tell us about the Mishaq e Madina
Name the Sahi Sitta
Name the Umm ul Momineen
What do you know about the Bait e Rizwan

Pak Affairs
Name three female leaders of Pak Movement (apart from Fatima Jinnah and Begum Liaquat Ali Khan)
Name three Baloch and Pakhtun leaders of Pak Movement
What was the M. A. Bogra formula
Elaborate Maulvi Tamizuddin case and Doctrine of necessity

Various questions on structure of government and role of different institutions and how they function. For instance ECP, CCI, Senate, Auditor General, Baloch Levies etc. Plus a lot of GK questions.

Then a lot of the interview is tangential to the profile of each individual candidate. Ones educational profile, ones work experiences, ones optional subjects, and psychological test report are all factored in.

Hope this helps.
