I have gone through NBP test a few days ago.
Moreover, My LDA test was almost the same but Bank's tests always supposed to be easy.
So you can believe that the information could be credible.

NBP test was conducted by Institute of Bankers Pakistan. Most of Bank's tests are conducted by this institute. Following were the important categories in NBP test, so you can think that same would be the pattern of your this test as well.

Names of capitals of countries
Names of Important Peninsulas
Names of important straits
Names of important rivers, oceans
Names of important world personalities
Names of presidents of the countires
Important peaks of the world
Names of International News agencies
Air lines of the world
Intelligence agencies of the world
Currency units of the world.
Head quarters of the International Organizations
Important Banks of the World
Report of State Bank
Inbflation rate of Pakistan
Unemployment rate of pakistan
Growth rate of pakistan

Following are the four main areas of Bank's test
1. English (synonyms, antonyms)
2. Analytical Reasoning (comprehension)
3. Maths (Basic plus/minus, percentage, ratio)
4. Computers (Basics about IT MS word, power point, excel)

weightage formula will be following I think
English 30 marks
Analytical Reasoning 30 Marks
Maths 30
Computers 10 Marks
