Earthwater interview questions

Applied through LinkedIn, phone interview with Marketing Manager then was invited to an office interview with the Marketing Director and Manager. Was asked basic questions then asked to prepare a short presentation to display my skills basically doing a social media analysis of EarthWater's current social media, and after my presentation was sent in, theyd reach a decision. I completed this by the deadline then it was radio silence for weeks. I reached out to the Director and she said she hadn't even taken a look at my presentation then asked what my salary range was. The job posting said $40K-46K so i said that was my range. She said they only budgeted for $35K. She called me back and said the president of the company, Cash, wanted to meet me. I went in and he watched TV during my interview and paid no attention to me. He said he'd be in contact because he was interested in hiring me. I recieved an email if i could come in ONE MORE TIME to meet with everybody. a few hours before the interview, i received an email that they decided to go a different route with the position and the position was cancelled. I got a call that night from the Marketing Director apologizing and making an offer for $30K. Of course I turned it down. A few weeks later, content from my original presentation was used in their social media. This company is crooked. DO NOT WORK HERE.
