In 5 sentences, please write your expectations from the class and from the teacher.

I wish I can speak like a professional person. So if I use childish word or low level English, I want my teacher to lead me to speak more elegant way. Also, I am looking for a job in a global company, so I have to prepare for my English job interview. So in our free-talking time, I would like to practice answering some questions which might come out in the job interview. I would be happy to hear short comments about my answer too :) Thank you!
