Hi vienna,
I tend to agree with etaoin, I think JiaYing is a fine name, but far be it from us to stand in the way of your interview.
It occurs to me that many of the names mentioned are not strictly English. Some are foreign but have English spellings, some are common in English with a particular pronunciation but are used widely in many countries. 'Judith' for example, has numerous pronunciations - so this might sway your decision - depending on whether you intend to use the name largely on paper or in spoken language. It might be important to consider who will use the name and how practical it will be for your purposes. There are many J names ...Joy, Jane, Josephine, Jeanette (or Janet)
I've always liked Janina and Jasmine, but really only with a soft J.
Good Luck choosing one!
