The only three true job interview questions are:

1.  Can you do the job?

2.  Will you love the job?

3.  Can we tolerate working with you?

That’s it.  Those three.  Think back, every question you’ve ever posed to others or had asked of you in a job interview is a subset of a deeper in-depth follow-up to one of these three key questions.  Each question potentially may be asked using different words, but every question, however it is phrased, is just a variation on one of these topics: Strengths, Motivation, and Fit.
