On April 9 episode of SBS' television show 'Delicious Rendezvous', HeeChul revealed the kind of jobs he had before he became a K-pop star.

HeeChul said, "I was working at a factory when I auditioned for SM Entertainment. It was a factory that produced televisions."
He went on, "I didn't think I'd pass the audition, but I did. Just like that, I became a trainee at SM Entertainment from a factory worker."
