Dear Ajeetaamrani,
i really appreciate your kind advice. yeah you are absolutely right but the problem is,i was interviewed by some government officers not by any multinational company. Once i was interviewed in two departments of Serena Hotel Islamabad both times i was interviewed for an hour.i have 3 years of experience in government sector i know them very well. i know you are right but my point is, ZTBL interviews were just a formality.
