The extension of the undergraduate course has nothing to do with the interview.
There are four main reasons for delaying graduation:
First, due to physical reasons, candidates can apply for suspension from school to postpone graduation if they have physical conditions that affect their study during their study;
Second, they can't meet the graduation requirements, such as failing the exam, failing to complete the credits and failing the thesis.
Third, students' personal reasons, because the law stipulates that college students can get married, some students who have not made good plans have completed major events in life ahead of schedule, and some female students have applied for an extension of graduation because they are pregnant after marriage and are not suitable for continuing their studies;
The fourth is to avoid employment. A small number of students are not ready to enter the society, so they choose to postpone graduation.
