Applied at Zyter Assist Inc. for Unknown

I received a call from a rep at Zyter Assist Inc., which I believe is connected to Veteran Affairs and Deloitte. They were quite pushy about scheduling an interview for tomorrow and seemed eager to finalize the hiring process. However, I'm feeling uneasy about the legitimacy of the company and the call, especially since the phone number (+1 332 area code) didn't yield any results when I searched for it. I want to be cautious before providing any personal information, so I'm seeking advice on whether anyone has experience with this company or if they can confirm its legitimacy. I also noticed that asking for W2s and other personal documents before an interview is a red flag, which has me concerned.
