FunGuy Studio interview questions

One of FunGuy's recruiter contacted me and told me if I'm open to opportunities and I said I'm always open for new stuff but I really like it in my current company so I'm not accepting offers lower than double my current salary and I told them my exact figure. They say money is not a problem. After the initial interview, they scheduled me an interview with one of the higher ups to describe what sort of experiences do I have in game development. I aptly told them my professional experience and they scheduled me an interview with the CEO a week after. Almost same process. Then they told me to come to their office to look at the job offer and this is where I got disappointed. They offered me a salary way lower my demand. They should have coordinated internally and told me earlier that they can't afford my salary so we both didn't have to waste time with the interview. It's been a week now and they haven't kept in touch.
