People's identities were much more localized. People were not citizens of a nation at that time. Many peasants were serfs and their identity would be tied to their lord. They might also identify as a member of a small city. A noble's identity would be tied to the ruler he served. Most people didn't have job or profession in the modern sense of the word. Religion would be key to all people at this time.

Religious affiliation would be first probably furthered with which administering district of church to which they belong. Then you'd have what these days we would refer to as ethnocultural like Slav from near this bigger town or geographical landmark and subject to which political authority deriving their legitimacy from their church. Nationality as we understand it did not exist before the rise of the modern nation state when governments more or less created nationality to more effectively tax and conscript subjects. Hobbies and personal interests would not be discussed because without some form of documentation you would be a mistrusted outsider not from their own, tightly regulated, religious community.
