An experienced interviewer takes care of many things: builds hypotheses, selects interviewees, composes invitations, schedules appointments, sets the stage, and, of course, writes an interview script. Any of these preparations can go wrong, but the script failure means all the effort is in vain.

Then, there is a chance they’ll smooth out other potential shortcomings.
We’ll talk about 12 kinds of questions explained with examples. The first part includes six frequent mistakes and how to fix them. The second part presents six ways to improve decent questions and take control of difficult situations.
