A candidate's ability to take the initiative is one area often explored. Proactive behavior questions help the interviewer see whether a candidate has taken charge or not in the past. Some questions that an interviewer might ask are "Have you ever performed a task that wasn't your responsibility but needed to be done? If so, what was the task and the outcome?" or "Please provide an example of a project you initiated on your own. Why did you take the initiative? What was the outcome of your actions?"
