I applied in-person. The process took 3 weeks. I interviewed at Army Welfare Trust (Islamabad, Islamabad) in Nov 2014
Interview
Interview candidates were shortlisted and called for interview on a specific date. A panel of 4 personnel of interviewers were there. They asked some basic questions about the current job. After further shortlisting the remaining personnel were again called for detailed interview. The person finally selected was issued the appointment letter.
