Can advise?
Am current jobseeker, Singaporean but grew up in Tokyo. Graduating next year with top score from top japanese uni (Todai/Waseda/Kyoto)

Got offer already for a foreign investment bank (FO but not IB position, pay around 6k)

Have received call to interview with MFA and EDB. What should I expect? If I join these organisations, will I still be able to progress as a non-scholar?

GF is also Japanese, will marrying a foreigner affect my career?
