@Mehreen: Reference should be given of that person, who is working in company in which u are applying. or working in same line of business.
Employer wants to verify your info, thats y they asked for references.
Name of your referee, CNIC #, contact # nd designation
if u have no reference in applying organization that mention the reference of any family member(if u think that it works) or preference should be given to person of public sector.

Gud luck nd feel free 4 asking more!!!
