A wonderful day

The day for me Today was really unbelievable! I'm a fresh graduate I'm newly graduated/I have just graduated and my major is (or 'was' if you are finished with school) Japanese. I have passed the highest Japanese text test for the international grade one in the past one year (it might sound more natural and clear to say something like: "This past year, I passed an internationally certified Japanese test for grade one proficiency"). But now I will go to an european a European company for work. In the interview, I used my poor spoken English chatting with the franch a French person. I needed to complete (complete what?) with the persons whose major is was English. When I got the phone, I really couldn't believe it because the company is on the global top 500 list. I'm regretted regretful that my mayor major can't become a part of my job (you could also say: 'It is too bad that I cannot use my Japanese education for my job'). But now, I kown know that I need to improve my spoken Englisn as soon as possible.

Congratulations on the interview, and good luck! With study and practice, I am sure you will become more comfortable with English!
