两年失业有点长,讲师面试莫彷徨.面试就是听你说,会说才得好工作.

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.

能教本科生计算机或电子工程的你,肯定具有高素质能找到更好的工作.
However, you need follow a right way.
Good luck for interview!
