Last time test was very easy and i was selected for this post but didn't join. I would like to share some of my experience of total hiring procedure.
Result was announced within 15 days. We were interviewed at UBL Towers, Blue Area, Islamabad. I was called at 3
0pm but interviewed at 6
0pm. Most of the candidates were from QAU, Islamic, University of the Peshawer, and NUST. Some were from Arid Agriculture, Rawalpindi.
Interview was a simple discussion related to educational backgound, experience, and willingness to work in Islamabad/Rawalpindi. One thing that i would like to add is that UBL's selection process is fast.
Go through last year's post that contains test questions. You will get better idea.
Wish you best of luck..
