My interview for NAB in past was taken by the committee comprizing of a Maj Gen, two Brigadiers and a Lt.Col.

As far as I remember the first question they ask was; why do you want to join NAB and what can you do for us? I gave a detailed answer and honestly speaking my reply was all extempor.

Second question was; why do people do corruption and what should be done to eliminate corruption from govt institutions and the society? Again an extempore and detailed reply.

Third question was from my answer to their second question. They got a descriptive reply.

Forth question was: how did you learn such a good English? I simply took it as a compliment and thanked them with smiles.

Last quetion: do you have computer skills?

And thats all.
