Run for your life!
Assume the option package they're dangling in front of you is or will be worth $0, then reconsider whether you truly want to be a part of the company.
Decline the interview! Run! Run as far and as fast away from this place as possible. You are interviewing to sell your soul, mental health, physical health for horrible pay and treatment. If you're adamant, the interview question they pose are not unlike the ones you can find on the internet. They are not creative in their interview questions...
Wait until the market stabilizes and these guys fail. They're just a marketing team with snazzy names and the first brand to blow up.
Don't this place is terrible. Don't let them sweet talk you it's all an illusion. It's like working in the circus without the fun, all clowns!
Don't be shy
