dear all my background is engineering
well in 2010 I have applied for this.My test centre was PAF rawalpindi near Saddar
Intelligence test and general engineering test was held at the same time.Candidates were called in the test room and a computer was assigned to each person(both computer based test).First intelligence test started(picture,number series etc) and those who cleared intelligence were allowed to start next test,those who failed in intelligence test left the hall.I remember we were nearly 60-70 before intelligence test and after
it I counted only 12 left.Now general engineering test was like GAT general(math,english ,analytical/logical).after I cleared general engineering test the examiner said jao ja kar apni medical ki date le lo.

I hope this will helpful for those having engineering background
