The members said, "After we were on 'Produce 101,' our dorm was brought up from a semi-basement to an aboveground.  Also, through this program, we were able to learn how to use an in-ear and a microphone.  And we also learned how to look at the camera."

They were asked about the intense competition on the show.  The girls said, "Seriously, behind the cameras, there were more friendships than competition.  We were in the same situation under the same circumstances.  That's why rather than feeling jealous, there was more sympathy and empathy.  Sometimes, we purposely made it seem like we were more competitive in front of the camera."
