No Appointment MD interview questions

Received a call from an office manager of the company on a Wednesday afternoon who found my resume online; I was asked to report for interview the following day of Thursday at 10:30 am. Met with the office manager at the business's T-Bird location. Had a great first interview, although was not able to ask questions I had prepared for the employer, and also was not asked much questions by the employer. I was invited to meet with the COO the same day. After interviewing, I sent out thank you emails to both participants. I left a message with the initial office manager the following day to collect status on the decision of my interview. I did not receive a call back. I sent an email the following Tuesday to the COO and it was also ignored. I did not feel good after meeting with the COO. When our visit began I realized she was unaware her office manager had contacted me for interview, and I was treated like I had applied at random to the company looking for a job. I knew at this point I had totally wasted my time. I felt like they just called me to waste my time.
