US remote work scam using credit card balance trick.

I had a shipping company that had a project manager role that was remote. Their address was in NY. I have experience as a PM and the pay was 80k They had a website that looked legit and had me do several phone interviews. Then, take online tests every few days. The red flag was when they asked me to use my credit card to purchase some expensive items, and they would pay me back. But they wanted to do it on a card that had a balance. They said the higher the balance, the better. They were going to pay my balance 1st and then have me purchase that amount in the items. The scam is they would have most likely sent the money, then reversed it days later, leaving me with my original balance and the new items balance. Later on when I looked up WHOIS company website, it came up as Ukraine. They got $0 from me, but it was quite elaborate and seemed legit until the CC thing.
