Ventajas
- As a new grad, if you get lucky and get placed in a team that operates internationally, there will be opportunities for you to travel abroad. - If you get lucky and get placed in a team/division that isn't predominantly Japanese, then you'll get to meet smart, talented, and like-minded foreigners from all around the world who are open-minded and have multicultural mindsets -- two qualities that are important when working at a global company. Additionally, you'll get to form strong friendship with your foreigner doukis, especially because you go through the same/similar hardships together (esp. ones that arise from language barrier and cultural misunderstanding). Notice I say "if you get lucky."
Desventajas
Basically, the reverse of the pros listed above. Additionally: - Depending on where you get placed, you may get asked to do a lot of English translations almost every day, even though it's not part of your job. - Low pay. Forget about getting a promotion or a significant pay raise. It'll take many years until you get it, especially because Rakuten is based on a seniority wage system (HR will tell you otherwise, but trust me. That's how it works.)
