Ascent Bio-Nano interview questions

I sent an email with a resume, references, and transcript. Was emailed the next day by the CEO requesting a phone interview. During the phone interview, she asked me questions and asked if I had questions. At the end of the phone interview, she told me that she liked my qualifications and asked if I would be available the following Thursday afternoon to have an in-person interview. She told me that she would send an email later detailing when and where the interview would be. I waited until about 48 hours before the in-person interview was supposed to held and had not received an email, so I sent the CEO an email asking if she had decided on the time and I never received a reply. On the morning of the scheduled interview date, I called her on the number she had used for the phone interview. I asked her if she was still planning on having the interview that afternoon, but she said that she couldn't because she had a meeting planned for that afternoon, but she said that she'd email me some information. It's been a week and I still haven't heard from her. I understand if she didn't want to continue the hiring process, but she told me specifically that she wanted to set up a time for the in-person interview. The only indication I got was the lack of a response on her part after that phone interview, which put me in an awkward position to have to make a subsequent email and phone call. Overall, I wish that the company had been more honest and straightforward with their intentions, instead of putting me in the awkward situation of having to send the follow-up email and phone call.
