An Experienced Member Story


矢口 浩平 Kohei Yaguchi

Senior Director

Project development is mostly communicated through a chat web service, so you do not have to rely on spoken English. And if you do not understand something, it is easy to look up!

In an environment where you use English everyday, you will naturally acquire English skills by communicating repeatedly on a daily basis. I started with a TOEIC score of 285, but in less than half a year I was able to manage a team of five Indonesian programmers to complete a project.
