Pros: - Free lunch - Cool office - No Japanese skills required

Cons: Rakuten Mobile hired too many inexperienced people. There was a lot of bureaucracy. I was assigned to work in a team that didn't need more headcount. The manager didn't know that I was joining until a week before. Later, I learned that I was selected to join that team only because HR said so. Two months from then, I tried to move to a team that needed more people and also my skills. Managers on both sides agreed to have me moved. Still, HR said no.

Pros: We could know a lot of domain knowledge.

Cons: It's not easy to work for a long time.

Pros: Teams are a good size. Good company perks. Decent pace of work.

Cons: Japanese business customs involve lots of documentation and meetings.
