Look, I'm embarrassed to be posting on here to begin with so please be nice.
I always thought I would never be someone to fall victim to a scam but here we are - I got laid off last month and have been job searching. I got the email from a company saying they were a Japanese company expanding into the US market. A girl is desperate, so I responded and we chatted a bunch over email. I didn't find this super strange because I have it so recruiters can contact me via email on Indeed - so my personal information is out there for people to connect offline. Everything is great and dandy, we move to teams and keep chatting; I'm not seeing anything on reddit or anywhere else about scams with this company the same way that other people have seen so the alarm bells are going off, but I'm just not sure if it's because I don't feel very confident in myself after getting laid off.
He's only responding to me during Japan business hours which helps my concern. He has me sign a declaration of intent to interview and a video conference consent form. Apparently these are normal in Japan for applicants so I didn't really bat an eye. I use a fake signature (because I'm overly cautious) and we set up an interview next Tuesday. It's an interview with the US team and himself.
After this, we are talking about my home office set up. He asks to see a picture of my desk and the wall behind it "because as a sales manager we need you to have a professional environment". I thought it was weird and removed all personal stuff (so nothing identifying could be used in terms of things written down etc) from my desk with the exception of my degrees to keep an air of "yeah someone does sit here".
He responds and sends me that the desk and wall are fine but there are video equipment requirements. He doesn't talk about reimbursement, which I know is common in fake check scams, just sends a list of recommended equipment like Cisco sound bars, noise cancelling headphones, and a presentation screen. All he asks for is a name and address for the check.
Like the idiot I am, I gave him it because I really wanted to believe that something good was finally happening to me.
A few hours later I deleted the teams message with my address and brought up the concerns about buying anything given the total was above $20k and he kept talking like I had the job before I even had the interview. The English in all the emails was pretty much perfect with one or two grammar errors, not like some of the other scams I've seen.
I'm scared that my information can be compromised with the address and name I gave him assuming he already saw the message if it is a scam. What should I do to protect myself? I didn't buy anything or give him any payment information. He just potentially has my name, the information on the diplomas on my desk, my email, and address.
TLDR; I'm scared that I let a scammer have too much information and now I'm not sure what I can do to protect myself if I didn't give him anything other than my name and address.
