hey, i just got my offer letter and would be happy to help you out.. the application process requires you filling out a form online which includes your long term and short term goals, why you chose to pursue the course at imperial and a personal statement about yourself. The interview is a Skype one, and try to be as natural as possible- they will ask you about what marketing campaign you find interesting and why, what you plan to accomplish after you finish the course, some basic questions about marketing. I think the best way to stand out is to be yourself, put across what you're passionate about and why it has led you to choose the course, also do some research on the person interviewing you and some of the lecturers e.g one of the marketing psychology lecturers at the university's thesis was the basis of a big bang theory episode lucky for me she was the one interviewing me. It is a pretty competitive course about 1200 people apply every year and about 160-180 people are chosen. Let me know if theres anything i can help you with
