Hello, I would like to ask if there is any presentation/project/portfolio required in order to show the level of skills one has and if, what should be in there? Is there any interview included in admission process? Thank You in advance

For ACS there isn't such requirement. You might be asked to join an online interview, but that is not the case for everyone, I guess it only happens if the academy feels you might not be the best fit for the programme and might need to ask you a few questions...
