On the February 7 airing of SBS Love FM's 'Kim Chang Yeol's Old School', a listener sent in a question asking Red Velvet for tips on auditioning.
Yeri answered, "I auditioned when I was in 5th grade. I searched 'SM Audition' on the web." She continued, "It stated you have to wear a headband for SM audition. So I permed my hair and wore a headband for the audition. It also stated that I cannot be only singing SM songs so I prepared songs by JYP artists. But at the end, the songs they made me try singing were SM songs."
