Analysis of interview.

I had a interview 9 years ago.
And another interviews have existed for 9 years. That is not job interview, but interview of some certification.
Anyway, the yesterday's class was awesome. I have never done it before.
Eye-contacting each other, recording myself and showing that recording file.
Everything was funny for me but there was instructive very much.
Although I have a job, I think it is useful to speak English organically.
Throughout the class, I have learned my attitude, my tone, my habit while I was talking.
It was totally helpful for me.
