Generally what I'll do is look for the website
https://realventures.com/
Then see if the people exist, the person I was chatting with has a LinkedIn and Facebook profile (and not just it existing but actual activity).
Search the address, there are two offices that seem to fit the bill.
But job descriptions are vague, offer after an online interview.
I don't have to pay anything, so it's not an investment scam.
I mean sure companies search online recruitment databases, and let's face it, I am pretty awesome, who wouldn't want to work with me?
