Oh, sorry I misread your response so i deleted my initial response. In Taiwan, it is usual to have an interview, unlike some other SE countries. The interview is usually just to clarify what you have submitted and i found it the easiest part of the process. Taiwan focusses on your employment, income, business registration even for SPERs. If you want to apply for SP, other embassies are easier., Jakarta, Manilla, Vietnam.
