PM role at PayPal

Hi, I have been reached out for a PM 3 level role in PayPal. Need help with below things from Grapevine family.

1. What should be the salary expectations if I am having 8 years of experience post MBA.
2. How is the work culture in PayPal, Banglore location to be precise.
3. How does the hierarchy for a PM look like in PayPal, while the role is PM 3 role, not sure if I should ask for a higher designation.
4. What does the interviews look like, how should I prepare?
5. Any other feedback on PayPal would be helpful.
