Behavioral interviews are often conducted by employers to asses how a candidate would handle certain situations that may arise within the company. The advantage of holding this type of interview is that it offers some insight into how a candidate has dealt with past problems.
Answers to behavioral questions are typically in the form of a story. It is important that you, the interviewee, describe the situation, the action taken, and the results in great detail. Choose your stories wisely and make sure they answer the question appropriately. The interviewer needs to understand what your thought process is so they can establish if you will be a good fit for the company.
