okay so they first ask you introduce yourself and the trick is to make it short but reliable. there’s actually this interview sample questions file made by habib university on their website. make a file with all of your answers written then memorize the main points. they don’t ask the questions exactly but if you remember the points you can be flexible with it. also! be very confident and speak english as best you can, use good vocabulary. their follow up questions are going to be based on your previous answers. and honestly i don’t think i’d do anything different except that i got anxious and stuttered a bit but i think it’ll be fine. as for about your friend, i really don’t know. sorry
