This mind map works as a handout for students and contains prompts for most questions that might come up in a job interview. The teacher should go through the questions and possible answers with the students, then give them time to think of answers themselves (in class or as a homework). Then, you can conduct the practice interviews extremely easily.
I created it because I had several students leaving university and looking for jobs, so I researched all the interview questions, split them into relevant topics (about yourself, education, experience, etc), and typed prompts for all the questions.
Any native speaker will be able to work out the questions from the prompts - e.g. in the "Yourself" section, "Summary" = "Tell me about yourself" or something along those lines, "Strengths" = "Tell me some of your major strengths" etc - I have left it loose so the students can phrase and understand the questions themselves.
It will be easy for the teacher to go through the possible questions with the students, and then to watch them come up with the exact questions and answers themselves based on their own experiences.
