Behavioral Interviews

What Are They?
Many companies use a technique called behavioral interviewing. It's premised on the notion that your past performance is the best predictor of your future performance. While traditional interviewing asks you to state opinions--"Tell me about yourself." "What are your strengths and weaknesses?" "Why do you want to work for this company?"-- behavioral interviewing is reflective. Specifically, the interviewer wants to know how you handled challenges related to the skill sets the company requires for the position

How Can I Prepare?

Situation, or
Task, leading to the
Actions taken or not taken by the applicant, and the
Results or changes caused by these actions

For example:
Interviewer: Give me a specific incident in which you had to address a team member problem.
Applicant: Situation/task: During my summer job, I had to provide engineering support for experienced operations personnel, but the plant foreman would not allow Operations to make a change I recommended. Action: I sat down with the foreman and sought her assistance. Result: Once we reviewed my plan and revised it to address her concerns, the plan was implemented.
