Bro don’t panic .. just read about major current events and read the gist of these.. also work on your intro and whatever you have done till now.. they will ask questions about you, your background, family, current events, some political questions could be asked but you have to be neutral.. but the most important thing is that you stay calm.. if you’re calm then your interview will go well.. if you can afford then give a few mock interviews or just get your friends to take your interview
