When you interview, the teacher already knows that you are a cross-candidate, but for many teachers, they generally don't give you too much trouble with professional foundation. Most of the re-examination is because the teacher thinks that the candidate is not suitable for academic research in this subject, which is not discrimination. Postgraduate entrance examination should select people with a certain knowledge base, good thinking ability, enthusiasm and potential for scientific research. The setting of the second interview is also to better understand the students' scientific research ability and make the last pass, rather than just deciding whether to accept according to the results of the initial test. On the other hand, the graduate students recruited should be brought by the tutor, and the tutor is more concerned about whether the suitable students can be selected.

Although generally speaking, teachers will not be too difficult for students who take the cross-exam, you still need to understand the most basic questions, such as the bibliography of the professional courses you apply for, the relevant books and documents you need to read, and when you answer, secondly, you need to check the research direction of relevant tutors to cater to the teacher's "taste". Of course, you can't completely ignore your undergraduate major. In case a teacher is interested in your major, he just has this knowledge.

For cross-disciplinary students, you must think clearly about this problem yourself. If you blurt out that the original major is too difficult, not good for employment and has no future, but the major you applied for is good for employment and eager to learn, it is purely a disgrace to yourself. Therefore, I suggest that you start from your personal interests, ambitions or ideals, that is, show your love for cross-majors, have a deep understanding of the major and school you are applying for, and then extend it to the fact that you are capable even if you apply for cross-majors, highlight what is the greatest advantage of your major, and emphasize the help of your major to graduate school.
