There's no formal preparation needed here. All you should think about is why you want to do this program, and how it could benefit you and your goals.
We know iX is a big decision. There will be ample time for you to ask questions at the end of your interview so we can ensure you have all the info you need.
We'll call you on your phone, or schedule a Zoom call. The call will last around 10-20 minutes, but there's no strict time limit if you have questions.
