According to the query of Baidu Library, when filling in resumes or interview forms, it sometimes meets the requirements of filling in parents' occupations. If you don't want to disclose your parents' professional information, there are some ways to avoid or politely refuse. For example:

You can choose not to fill it in, or write the words "none" and "inconvenient to disclose", indicating that you have no intention to answer this question. Generally speaking, unless it is a special job or unit, this question is unnecessary and will not affect your interview results.

You can fill in some vague or general information according to the actual situation, such as "on-the-job employees", "freelancing", "retirement" and "farming", and you don't need to specify your parents' work units and positions. This can avoid lying and protect your privacy.

You can directly explain to the interviewer why you don't want to disclose your parents' occupation, such as "I don't think this question has anything to do with the position I applied for", "I hope you can respect my personal choice" and "I think this question involves my family privacy". But be polite and firm, and don't appear stiff and sensitive.
