First you have to take the GMAT. If you can, get it waved (check out the website for details) because it really speeds up the whole process. When filling out your application, make sure you carefully craft your essays, personal statements, and letter recommendations. These things really matter. Do your homework. After you submit the application, wait a month until they ask you to interview. It can be in person or online. It took 30 min. They asked 10 questions and allowed me to ask questions as well.
