Hello

Gdpi is kind of a personal interview. It is not tough . It's more like self awareness. You should have basic etiquette of how to talk and express yourself. Your confidence and your set of communication skills will definitely increase or decrease your chances of getting selected. You may be asked to tell your favourite place from your home town or some visiting places at your hometown. They can also ask some general questions regarding elections as it is the trending topic right now. But be confident enough even when you don't know the answer just tell them the truth. Do not take help of lies.
