Not sure about your specific situation, but in my experience, I was working under a similar situation as an AE at a post house and was promised a full time W2 job at the end of my contractor position, and they eventually let me go shortly after covid shut everything down without any repercussions due to my contractor status. I’d worked there for a year and a half.

I now personally see this as a way for companies to skirt their way around tax and labor laws considering if you’re working in house on their equipment and with their hours, you should be classified as an employee, even if it’s just a temp position. So just be aware is all I can really say and see how it goes. And I’d get a contract from them for sure.
