Work / Salary for an experienced professional in an MNC (Lodz / Warsaw - Poland) [5]

Merged: Job opportunity in Warsaw - 3000 USD monthly enough?

Greetings,

I have a job opportunity with one of the MNC'S with $3000 USD gross as monthly pay.

Few questions.

- will I be able to get a two bedroom apartment for rent in Warsaw for 700 USD?

- what is the standard income tax and other deductions?

- If I have a work permit, is my wife allowed to take a full/ part time job?
