Phone Screen, 1 on 1, then Panel. Liberty Mutual uses the SAR approach to interview questions and they expect you to answer this way. S.A.R. is situation, action, result. The interviews are behavior based. They want to make sure you understand how you got from point A to point B with each situation. Where was the sales rep when you started working on them, what did you do to help improve the rep and what was the result when you finished working with them.
