2010年，Wendy參加了由Koreaboo和[[Cube娛樂]]共同舉辦的2011 Global Auditions，透過線上試鏡提交影片。雖然她並未成為最終贏家，但她從超過5000部影片中脫穎而出，成為15名決賽選手之一，這些人是由韓國歌手[[G.NA]]和Koreaboo親自選出的，並有機會進入[[加拿大]][[溫哥華]]的決賽輪，同時為[[G.NA]]的首場個人表演擔任開場嘉賓<ref>{{cite web |title=Cube Entertainment reveals finalists for 2011 Global Auditions |url=http://www.koreaboo.com/index.html/_/exclusive/cube-entertainment-reveals-finalists-for-2011-g-r3900 |date=February 23, 2011 |url-status=dead |archive-url=https://web.archive.org/web/20141008084834/http://www.koreaboo.com/index.html/_/exclusive/cube-entertainment-reveals-finalists-for-2011-g-r3900 |archive-date=October 8, 2014 |publisher=Koreaboo}}</ref><ref>{{cite news|title=First-year becomes K-pop singing sensation|url=https://thetartan.org/2011/3/21/pillbox/kpop|work=The Tartan|publisher=Carnegie Mellon|last1=Gupta|first1=Saakshi|date=March 21, 2011|access-date=March 1, 2016|archive-date=August 5, 2016|archive-url=https://web.archive.org/web/20160805231129/https://thetartan.org/2011/3/21/pillbox/kpop|url-status=live}}</ref>。

Wendy原本並未計畫參加[[SM娛樂]]的試鏡，但在2012年，她陪朋友參加'''S.M. Global Audition in Canada'''時，被SM的星探相中，並受邀參加試鏡<ref>{{cite news|title='한끼줍쇼' 레드벨벳 웬디 "친구 따라갔다가 오디션에 합격했다"|url=http://sports.chosun.com/news/ntype.htm?id=201812120100088390006357&servicedate=20181212|work=[[Sports Chosun]]|language=ko|last1=Nam|first1=Jae-ryun|date=December 12, 2018|access-date=December 12, 2018|archive-date=December 25, 2020|archive-url=https://web.archive.org/web/20201225124924/https://sports.chosun.com/news/ntype.htm?id=201812120100088390006357&servicedate=20181212|url-status=live}}</ref>。她回憶當時演唱了[[金健模]]的《서울의 달》（首爾之月），最終順利通過試鏡。此後，她進入SM娛樂成為練習生，並接受了不到兩年的培訓。
