They take your body measurements (Chest, Waist, Hips, Thigh and Arm) and if you measure within their specifications and have the height and proportions they are looking for you are asked for a follow up interview and are measured again. If you are within the same measurements and comfortable trying on clothing and lingerie they ask you your availability, expected wage, etc and will ask you to come in and have the teams who will be fitting on you try on clothing and compare the fits to current fit models.

It was pretty easy and straightforward. It was just taking measurements of your body. There are no questions really just looking at your body. I wouldn't stress about too much.
