兩年失業有點長,講師麵試莫彷徨.麵試就是聽你說,會說才得好工作.

Congratulation for the interview.
Focus on:
-- Dedicate work spirit;
-- Clear Communication skills;
-- Love teaching.

Prepare a good set of Power Point file, as a sample to show them how do you teach in a class.

能教本科生計算機或電子工程的你,肯定具有高素質能找到更好的工作.
However, you need follow a right way.
Good luck for interview!
