I also applied Full Stack Developer (No Japanese Required) Interview on my country. I found that LINE interview is good for fresh student because their technical question is not practical and quite look like my master degree homework question about the theory in I/O, network. I had 15 years+ experience in IT and 10 years in development cross-thought dataware house, ETL, windows, web, frontend, backend experience. But LINE doesn't focus on how's my experience can be contribute to their company, but just keep asking me question of (How to do), (What to do) brabrabrab to their product. Although they doesn't need to know Japanese, but they require the applicant have native level English. It is very confuse they want a Country who speak Chinese but also native on English. Less
