On the December 11 broadcast of tvN's 'Problematic Men', the cast held an intern audition with 10 bright, young, intern applicants!

Stars who appeared to impress the cast members of 'Problematic Men' with their brains included: singer/song-writers Aivan and Siyoon, Han Min Se of Long D, UNIQ's Sungjoo, SF9's Inseong, HOTSHOT's Yoonsan, IN2IT's Hyunwook, HBY's Taro, and models Park Chan Gyu and Joo Uh Jin. 

Each of the intern applicants first introduced themselves and showcased their impressive education, multi-lingual skills, special talents, etc:

The 10 applicants were then tasked with solving quiz problems, while the 'Problematic Men' cast members judged each applicant's problem solving skills and approach from the sidelines. 

Among the 10 intern applicants, Han Min Se, Aivan, and Inseong impressed by answering the quiz questions efficiently and creatively. Han Min Se and Aivan solved 2 problems each, while Inseong solved 1 problem even faster than the 'Problematic Men' cast members.

Finally, when the time came for the cast members to choose their final intern, Jun Hyun Moo suggested that they select two, as all of the candidates showcased excellent performances. The first choice candidate turned out to be Aivan - chosen for his confidence and brains, as well as for wits. The honor of the second choice candidate went to SF9's Inseong, who couldn't hide his surprise when his name was announced.

The two interns will be working with the cast of 'Problematic Men' for the next 2-3 weeks. Congratulations, Inseong and Aivan! Check out clips from this week's 'Problematic Men' above.
