Walgreens Customer Service Associate interview questions

Describe a time when there was difficulty communicating between you and someone else (I was asked this question at EVERY STAGE of this application process and I wish I knew why this had to be brought up). Describe a time when you were flexible/solved a problem/dealt with a difficult person/customer

Give an example of a communication barrier that you had to overcome. Give an example of teamwork that you took part of. Give an example of a time a customer was displeased, and how you took care of it. The questions follow that vein. They also ask to elaborate (what was your part, what did you do, how do you feel your action affected the overall outcome, and so on.)
