Like PPSC fpsc does not send sms and email upon selection and final result come after two to three years so you need to mention the address and contact no which should not be change to get aware of the result.Due to this reason some candidates may couldn't be able to join because they are not aware of their selection.

As per recruitment process you need to go through all key concepts of computer science and go through previous past paper of similar post. You need to prepare all topic conceptually and practice relevant mcq from mcq books like dogar online site like sun foundary etc.
For interview you need to watch css mock up interviews of css toppers. It will help you how to give relevant answer and how t9 handle differently situation.Although FPSC general recruitment interviews difficult level far less than CSS but it helps.
