As many of you already know, you have to go through an audition process to get one step closer to being a singer in Korea. After the auditions, you are a trainee. As a trainee, you learn acting, singing and dancing under your company. Audition clips of many stars have been released before to create laughter or let the star reminisce. The audition clips of SNSD's Hyoyeon, Seohyun and Yoona have been released on few of the variety shows before. However, new videos of SM Entertainment artists as trainees have been released to the public. In these videos, you see SNSD's Seohyun, Yoona, Yuri, Sooyoung, Jessica, Super Junior's Kibum, Heechul, Kangin, Yesung, Hangeng, Sungmin, Eunhyuk and TVXQ's Yoochun, Yunho, Jaejoong, Changmin. They all look more at ease back then even though they often talk now about the stress they were under during those times. They all look relatively similar to how they look now but Yuri looks quite different with her braces. Netizens wrote,

"They're all so cute. It's funny to see them before they were stars." "Yoona and Yuri looks like babies." "They all look so young."
