I applied through a recruiter. The process took 1+ week. I interviewed at LINE (Tokyo) in Nov 2016
Interview
Prepared resume documents (English CV, Japanese CV and Japanese work history sheet) prior to the interview and handed them over upon arrival.
First a short written test which covered IPv4 subnetting, TCP/UDP port numbers, Linux commands and a few general questions on servers and LDAP/AD. The questions were in Japanese but there was no need to actually write Japanese. The test was not difficult and I scored almost full marks.
After that began the main interview with 3 engineers. It was entirely in Japanese, quite technical but also relaxed, and I enjoyed it very much. It took a bit longer than expected which I thought was a good sign. They asked general questions like what are your main responsibilities at work, was the hardest issue you had been troubleshooting etc.
A few days after the interview I was notified that they rejected my application. The reason given was that while they liked my network and Linux experience, they want someone with more middleware skills. Which surprised me a bit since middleware was neither part of the job description, nor the written test and was only shortly discussed during the interview.
Nevertheless it was an overall good experience.
