I took an offer from the Line Fukuoka website, two days after I recieved an email with a coding interview Link on remoteinterview.io ( basic process : 1 week to start, 50 minutes test ). Test was really easy, if you are not chained with things like jquery. basic vanilla stuff to do. I've done the test, only one thing was incorrect, and I didn't do any extra stuff because I was late. I took time to read the questions, and the platform told you to send the result 10 minutes before the end "just in case of network error" because you have to upload your project. After this I just recieved an email telling me they took someone who matches closer to the offer. So I didn't reached the Interview.

Overall it was interesting. You know when you go prepare for the very difficult questions and you neglect the rather easy questions. It was really easy from basic callback functions to maps and javascript click events. So my point is dont go overboard and look at the little stuffs. The interview process lasted about 2.5 hours. There are two stages, the basic questions with an interviewer and an interpreter. Then the second stage is a technical test with one developer in my case.
