Forestadent interview questions

Brief phone interview. Then met with office manager and CFO. Both of them were very friendly. They called me to come back the next day to interview with the CEO. He was unprofessional from the beginning and condescending. Met with the Sales Director and the Marketing person. Interview lasted about 1 1/2 hours. I followed up with an email after no word for 2 weeks. CEO contacted me. Offered me the job for $13.50 per even though I had 20 years experience. He again was very unprofessional. I declined.
