LINE Server Side Engineer interview questions

Interview process had 4 stages. 1. CV screening 2. Codility Test with 5 questions - 3hrs 3. Video interview with 2 engineers - 2hrs 4. Final interview with 2 managers - 1.5hrs 5. HR interview - 30mins Coding tests were leetcode medium, and they asked questions about the coding test in the interview. Technical interview wasn’t difficult but felt like japanese language skills are required to work in this company during the whole process. Final interview wasn’t too hard, and it had some technical and behavioral questions. In the HR interview I couldn’t understand many questions because the interviewer couldn’t speak English properly. However at the end they rejected my application without any feedback. Even after politely asking, they refused to give feedback. After the whole process, I’m glad that I didn’t get selected because I can imagine how difficult it’ll be to work there without japanese language skills even if you have good technical skills.
