상반기 신입 공채는 크게 Client, Server, Cloud 직군으로 나누어 모집했습니다. 이번 채용은 라인 플러스, 라인 비즈 플러스, 그리고 라인 파이낸셜 플러스의 3개 법인에서 진행되었습니다. 쉽게 생각해서 비즈, 파이낸셜 플러스는 핀테크 사업을, 그 외의 서비스(메신저, VoIP, 클라우드 등)는 라인 플러스에서 담당한다고 생각하시면 될 것 같습니다.

모든 채용 과정은 비대면, 원격으로 진행되었습니다. 그러니깐 회사나 준비된 장소에 가서 시험을 보거나 면접을 보는 등의 일이 없었습니다. 다른 회사들에 비해 굉장히 빠르게 공채를 시작했고, 한 전형이 끝나고 결과를 받는데 시간이 2~3일 정도밖에 걸리지 않았습니다.
