The 28-year-old actress, who plays "sassy" Tamra on the show, said she "loves" dishing out zingy one-liners to the cast, particularly to Mindy Kaling, who writes some of the one-liners herself.
So, how did Xosha land a series regular gig on the show?
"I did a guest star on season one that was three episodes, and after it was done I got a call a few weeks later and they said they wanted me to be a series regular," Xosha told us. "I was really excited."
"Everyone was really nice and warm and welcoming, so I wasn't really nervous," she continued. "If I was intimidated a little, those feelings were crushed because everyone was so nice."
As far as one of the "coolest" parts of being on the show--aside from acting alongside Mindy--Xosha said the moments between takes are a blast.
"I think that's one of the cool parts of the show," she continued. "They play improv games in between takes and I'm just like watching. Not to sound corny, but it's like a master class and it's like I'm here too...what?"
