For the early interview, official website will be informed, and of course, it will be mentioned and explained when the school holds the MBA presentation.
Generally, 4-5 rounds of interviews are held in advance, depending on the pre-trial arrangement of the institution you apply for.
Pre-trial interview with Fudan as an example;
There is still a difference between on-the-job and full-time interviews in Fudan:
On-the-job projects need personal interviews and group interviews, and the personal interview time is about 15 minutes;
Group interview: 35 minutes, no leadership discussion, case analysis, English inspection;
The full-time program has only one personal in-depth interview, about 45 minutes, and it is in English.
The number of applicants is relatively large, the competition is fierce, and the difficulty is still somewhat.
