My Friend Asked A Quetion To Me About The Recruitment Process In Pakistan Army After Completing Graduation Degree. He Is Doing Electrical Engineering And He Wanted To Join Army Engineering Corp After Getting His Degree. I Told Him That It Is Not Possible For A Person To Join Army Corp ,if One Has Completed His Bachlor Degree From Any Institution Other Then Army Institution. I Told Him That Army Produce Their Engineers Thereself. But He Is Not Accpting That ,and According To Him Pak Army Recruit Engineers Directly Through Commission Exams.
