Practice makes perfect. Get a buddy to read off some behavioral type interview questions and practice answering. Choose questions that may be relevant to the type of job you are applying for!
Step1
First learn what a behavioral interview is and why some employers opt to use this method instead of the traditional type interview.
Step2
Try googling sample behavioral interview questions. Write down a few.
Step3
Jot down on a piece of paper facts about your work history. How you work with coworkers or your supervisors. Are you a multi-tasker? Do you work better alone, or with a team. Also jot down any projects, large or small you've done in the past. Be specific about them. Step by step go through the process of how you handled the workload.
Step4
Now that you've compiled some information about you, try to answer some of the questions that you've found.
Step5
Lastly, remember to think about the question and relay a personal work experience when answering. The employer wants to know about situations in your previous working experience, how you handled the situations and what the end results were.
