Carminati Consulting interview questions

Completely through text on the Signal app. They didn't do an in-depth interview, they just asked a couple of questions and then said I was accepted. I'm unsure if this is a scam at this point. I say that because the sent me a check via UPS for a bunch of money to purchase the computer hardware for my job. I took it to the bank, explained the situation, and now it is currently on a seven day hold. I told my contact at the company and she said that I should be able to access the money right away. She is not being real pushy, but she is trying to get me to purchase the equipment before the check clears. I told her no and that i will be waiting out the bank hold before moving forward. She seems to be alright with this. I will send an update once I know for sure.
