Practice makes perfect.
Practice your interview answers so you know them well and sound natural. The interviewer may change the order of the questions. Being well prepared means you’ll be able to smoothly answer any question they ask, whenever they ask it.
Time your answers.
This will help you stay within your allotted time. Your host will appreciate it if you don’t run over. Some use a recording program that will stop recording after a certain time period. You don’t want your interview cut short!
