Maurices Full Time Assistant Manager interview questions

I got to the interview and asked for the person that I had spoke to on the phone. She was off for the day and I stated I had a interview with her at 3. The lady states that I'm interviewing with her instead and it was scheduled at 3:30. She finished her project and met me about 10 minutes later. When we go into the office, she lets me know that the position that they are hiring for is part time sales associate that would be 10-15 hours per week. If the person who had called me earlier in the week would of stated that I would not of even went to the interview. Waste of time!
