There are two rounds of interviews. The first one is a group interview with other 10 people altogether solving a real case. The case is about a risk analysis on the exporting transaction. Because I majored in law, so I mainly contributed legal risks to the table, which turned out to be quite helpful to the team.
The second round is a one-on-one interview, but there was like 10 interviewers, shocked me at the very beginning. However, they are all very friendly, asking about basic questions, like why you want to join this company and what's your interests, etc.
