Pros: English and lunch are good. Good for average workers, not for engineers. But be careful about power harassment.

Cons: Ok, so everyone has lost their minds after the new LLM and ChatGPTs. All managers and executives have no idea about A.I. and now suddenly want to fix poor business processes magically just using A.I. To coders, managers just say, "Why don't you reduce your man-hours by using A.I. to completely handle this problem?" This is not just at this stage; the people in charge aren't pretending to be low IQ, but they really are. They completely copied the Mistral model and published it on Hugging Face as their own just to show that Rakuten is leading in AI? About Rakuten Mobile, so much power harassment is going on in the office to get Rakuten Mobile contracts in a shady manner.

Pros: - Very stable job - Very corporate culture

Cons: - Average salary compared to other big companies. - Bureaucracy exists in some teams.

Pros: * Lot of business areas that you can challenge. * Global company and chance to meet and work with talents.

Cons: * Many nonsense rules. * Business (sales) style is from a legacy Japanese company, which lacks data analysis and appropriate PDCA cycles.
