Orange interview questions

The technical interview was smooth and very good but the employer asked me to tell her about my current salary, I refused and told her it's confidential The employer told me that I would have to provide her any official document stating my current salary or at least the Bank SMS that notifies me about the salary deposit I told her I would check with my company and ask for a permission to disclose this information and get back to her when I called her back To tell her that this is not possible she told me she would call me back and she never did
