Anonymous Interview Candidate in Kasuga, Fukuoka
I applied online. I interviewed at LINE (Kasuga, Fukuoka) in Nov 2022
Initially, they sent me an online coding test. The coding test included an algorithm question and a design question. After the coding test it came to the interview part. There were two technical sessions and one HR session. The technical sessions included some basic computer questions, but mostly focus on past experience. There were also a few behavior questions and again a small design coding test. As for the HR session, it was just a formality to finish the entire process so I could not tell much. The whole process were taken online since I'm abroad and it took about three months I suppose.
- The technical questions covered computer network, operating system, Java core, algorithm and database. Explain a time you made a mistake and how you fixed it.

There are 3 rounds: - Online test: this round is not very hard, hard enough to see if a candidate is good enough to meet the company's general requirement or not - Technical interview: this round is pretty hard since it's focused on technical aspects of the up-and-coming position you'll be taking - General interview: no technical questions, mostly about your past experiences and your career path
- Questions are about topics like database, software engineering practices, operating system, Java core, programming concepts, algorithm and data structure

Anonymous Interview Candidate in Hakata, Fukuoka
I applied online. The process took 6 weeks. I interviewed at LINE (Hakata, Fukuoka) in Jun 2022
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.
- Asked system design questions by giving a scenario where a system had some performance issues and asked me to explain how to troubleshoot. Explain about a time you failed Unit Tests
