The point of a story is painting a picture. Adding additional descriptors paints a clearer picture in the mind of your reader. The author wanted you to call up in your mind's eye a man in a t-shirt, a man in a polo, and a woman of Asian descent. Maybe that's his experience with start-up interviews, maybe he wanted to force "diversity" upon the reader. Either way, the author chose to describe the Asian woman to you because he wanted you to picture an Asian woman. Why is that a problem?
