No matter what position you are interviewing for at PennyMac Loan Services, your interviewer is looking to hear what customer service means to you in your work and how you apply that philosophy in your everyday work life. In essence, they want to hear your story as to why solid customer service is important to you. Prior to your interviewer, be sure to really think about this question to apply what is important to you in how you go about your work. Whether you talk about problem solving or making people happy, this should be reflected in the work that you do.
