Bip!'s thing seems quite legit and he didn't ask anything that seemed even remotely useful for scamming or phishing (except my email at the end).
I highly encourage anyone who is kind of intrigued to go ahead and spend the 10-20 minutes (it really depends on how much you talk - I talk a lot lol) talking with him.
I know the problem is only 5-10 people will see this post anyway, but 5-10 more interviews seems like it will actually make a difference for bip! and you'll likely find the interview kind of fun
