Has anyone applied to the NTU summer internship 2026? (Global Connect)

I am thinking about applying to the computer science-related subjects at SNU for my masters. But I have the following doubts.

1. Are there English courses available?
2. Is it tough to get into SNU as an international student. I have less gpa (3.2/4), but I do have 3 first-author and 1 second-author research paper publications in my country's top publishing journal. Will my papers be helpful in getting a scholarship?
3. Are TOEFL or IELTS expected?
4. Is it compulsory to have a TOPIK score too?
5. Will it be easier for me to get a job there? and what about settling options?
