OMG guys! I just came back from my interview. I really think I nailed it! They were sooo nice to me. I'm going to write about my experience now.
The test were fine. the jpn test was only 1 part that lasted 1 hour, it got progressively harder. The eng is just like the sample test.
My interview~~ My panel consisted of a technology professor from univ, a japanese guy(i dont know what he does...), and our embassys MEXT cordinator. First they asked me some questions from my application, about my japanese studies, my short trip to japan, etc. simple. Then, the very knowledgable professor asked my some basic questions about my research, what is it about etc. typical at first. Then she started asking me more detailed question. I knew my research very well, so i was able to answer easily. She seemed very interested(eyes wide and nodding) with every answer i gave. then i think she tried to "me off balance." questions like, why is it important, why japan, how will people benifit from this, can you insure that other will reference your research in the future. Already knew the answers to these so i didnt hesitate to answer.
Afterwards, the interview got alot more casual. i was very relax. they asked some question about japan, some in japanese. I actually told them a story(in jpn) about how my friends and I went to a hanabi, and we got lonely, so we tried to flirt with some girls, and they all said no. The panel was laughing really hard. I even told them i liked anime! and they asked me what kind of anime do i watch. I wasnt able to answer all the japanese questions... there was one that i couldnt answer so i paused for a really long time, then the prof told me to say it in english haha.
they were sooo nice to me. especially the professor. most of the interview came from her, she even gave me some advice. i was very attracted to her b/c of her kindness even though shes like 10-15 years older than me haha(eww right?). i've been to plenty of interview and this one is my best performance BY FAR. even if i dont get the scholarship, this was such a great experience for me.
From my experience, here are my tips to anyone else who is still waiting for an interview: why japan?; KNOW your research; above all, be passionate!
