Forecasty.AI interview questions

They sent me an email saying directly that I was selected and they assigned me with a fundraising PPT making work, because they are looking for fundings now. They will review my outcome and decide whether to move on and then come back to me. It took me a week to make several beautiful slides. The part-time HR lady (they don't have a full-time HR) replied saying it's well received, we will come back to you soon. And she never come back. Now I feel my slides are stolen.
