Relativity Media interview questions

Met with the current assistant, then the director I would be supporting. The two people I met with were extremely friendly and helpful describing the position and answering any questions I had. After meeting with people in the department I was offered the job and a certain rate and asked for a bump in salary. HR was completely useless. They went through 2 days of salary negotiations, called and told me the highest number they were allowed to give and I accepted. After a week with no communication I was told that they were no longer able to extend an offer because of the requested bump in pay. HR is now denying that an offer was ever extended, even though the phone conversation with them I said I accepted the job and was told the department would be so excited to have me on board. Worst part is they knew I had another job offer on the table and I said I declined that job for them. HR is just covering themselves by saying no offer was extended. They should be ashamed. But in the end, guess I dodged a bullet bc if I see this from the outside who knows how the company is truly run.
