Zeta Offer related queries

Hello Everyone,
Posting on behalf of my friend.
He recently got an offer from Zeta. He has few questions.

1. What is the stock exercise period?
2. What is the notice period at Zeta? Is it negotiable? How easy is it to negotiate and what's the minimum notice period can go after negotiations?

Thanks !
