I was selected in MTO Batch 13. I have seen people have same queries which we have at the time of recruitment. I will answer the questions according to my experience in whole recruitment process from application submission till final selection.
Qus: My CGPA is less than 3 CGPA but %age is more than 70%, am I eligible?
Ans: U r not eligible for this post even if u have passed the test u will not be allowed to sit in Group Discussion. ( For NBP employees and employee son CGPA requirement is 2.8)

Qus: I have done BBA hons or BSc hons, am I eligible?
Ans: Absolutely not, I have observed that lot of candidates who are able to pass the test are not allowed to sit in group discussion due to the reason they have 16 years of education by doing hons.

Qus: My age is 26 years+ on 31 dec 2010, am I eligible?
Ans: Again absolutely not, I have seen a case last time in which a guy have age of 26 years and 6 days. He had passed the test but he is not allowed to sit in group discussion due to over age reason by 6 days. NBP management is very strict in the case of age. ( For NBP employees and employee son Max. age requirement is 28 years).

Qus: When test will be conducted?
Ans: Depends on shortlisting of candidates, Last time audit test is conducted after 2 months and general banking test after 5 months.

Qus: What are the relaxations given to employees of NBP and their sons/daughters?
Ans: All the Criteria's are same except age and CGPA.
Min. CGPA: 2.80
Max. Age 28 years

Qus: What is test Pattern
Ans: Last time following pattern is followed
English: 30 %
Maths: 35 %
Gen. Knowledge : 35 %

Qus: Safarish kitni chal sakti ha is recruitment main?
Ans: No chance of safarish. Totally merit base. I will say it will have negative impact. Dr. Mirza Abrar is Group head HR, and he is very strict and sensitive in this case.

In the last good news for females, last time nearly all the females who have passed the test are in final list of MTO Batch 13. No one is dropped in group discussion and final interview. I am confirmed about lahore and Islamabad center might be in Karachi 1 or 2 females are dropped. So females candidates have just to pass test. then there are 95 % chances that female candidates are in final list.
Males candidates will face tough competition in test and as well as in Group discussion and interview.
