Lucid Software Sales Development Representative interview questions

After having several conversations with a recruiter she said I was a great candidate for the job. She asked me for my schedule of availability. I quickly responded to her email and she didn't respond. A week later I followed up with another email and she still didn't respond. I called and left several voicemails, contacted her on LinkedIn, and filled out a general application online. No one followed up with me. 6 months later they ask me to come in for an interview. I arrived 15 minutes early for my scheduled interview time. They took FORTY-FIVE minutes to bring me in for an interview. I wasn't offered a job. But I think I wasn't very enthusiastic about working for the company and it probably showed in my interviews.
