Lowe's Home Improvement Customer Service Associate interview questions

I was already a contractor for a new product release and was asked if I was interested in permanent employment. Several of us were "rushed" through interview process because a new class was starting within a few weeks. Company already had information on customer service skills, phone manners, etc., but still had to go through several tests - typing while listening, typing accuracy, etc.

Filled out online application, assessment. Called in for an interview. Unprofessional because I waited 30 minutes for the first interview and another 30 minutes for the second interview. One was with HR, the other with the manager of the department. All behavioral and read off of a piece of paper. Did feel impersonal because of that. Questions are customer oriented. would be hard interview for someone with little customer service experience. (Name a time when you had to deal with a difficult customer, when you were criticized by someone, when you made a mistake). They choose candidates based on the total score. They rate each answer with a certain amount of points.
