> one about unlimited unpaid overtime

Am I misunderstanding something, or isn't this the definition of a salaried position?

> second one about losing all intellectual rights to ANYTHING done/written/created ANYTIME and ANYWHERE (including things not related to company's business and/or technology in own spare time, holidays and so on).

This also seems extremely standard (at least it's in every employment contract from the big tech companies), and probably exists more so to protect the company from extreme circumstances than anything else (although I am not a lawyer).
