Skillable Client Support Specialist interview questions

The interviewer was very unprofessional, her hair was a mess, she looked like she just woke up. I asked if she could give me more details about the job and what the company does, her first answer was "I don't know what the company does" before she started explaining, I was in so much shock that I couldn't even listen to her answer. She also started upselling the company to me by explaining how much she and the hiring manager love to communicate with Friends meme. and after the interviewer made me feel like I can get the job, I didn't get an offer. My speculation is that this interviewer picks candidates based on their own personal decision and not what's best for the job as I am over qualified for the position.
