If you take professional knowledge, it will definitely involve the accounting knowledge of public institutions. I have participated in several exams for accounting positions in public institutions, and my professional knowledge is reflected in written tests and interviews. Because the scope of review is not defined, there is no way to review it specifically. If you haven't worked as an accountant in a public institution before, I suggest you learn the main accounting knowledge of public institutions, such as the common sense of financial funds, the definition and use of zero-balance accounts, and the knowledge of budget and final accounts.
