Am I cooked?

Hey guys, I think I know my answer here but I need some confirmation. I went through an interview process and everything went really well, I got great feedback, I did perfect on a small project they assigned, and then after my final interview they told me about 3 days later that I’d basically landed the position, and that they needed a little time to sort out salary since they were hiring multiple roles, but they’d get back to me within a few days with potentially an offer.

The end of the week had come by and since they had given a tight timeframe, I followed up to ask if there had been any updates in the expected timeframe. They responded positively and just said they were still in the process of sorting things out in meetings, but that they’d get to me soon.

A week went by, then two, nothing from them, and now I’m not getting a response to my last follow up email. Does it sound like things have fallen through? If it was just delays and they stayed in contact I wouldn’t be so worried but considering with the 2 weeks of nothing from them I fear the worst. It really seemed like I’d finally nailed the perfect position so I’m a bit disappointed now that they’d get my hopes up and then ghost if that’s the case
