<prompt> Human: Hi all, I have a interview for a new job scheduled for tomorrow, and I need some hints from experts. Im working in my current job for around 18 months, and Im satisfied with it. But a friend told me about a position in another company. He also told me the manager who is hiring is his friend and told him the maximum salary the company will pay. Its around 150 higher than my current salary. So I applied and the manager called me 5 minutes later. I must say the job is serious, not a fake or something, its in a world class company. Im quite sure my skills and experiences fits perfectly for this new job I read the description, and I wont be in trouble due to lack of skills. I have 12 years of experience, Ive been working with every aspect they asked for the last 6 years, and Im sure my salary is around 20-30 lower than markets average the financial crise in my country hitted me hard last 2 years, couldnt avoid this drop. But even if I was close to markets average salary, this new job would still represent a 100 raise.Well, what Id like to ask is advice with salary negociation. How can I ask all this raise, or at least a huge portion of it? Id like to try all or nothing, I dont want a relative small salary raise i.e. 20 because Im very satisfied with my current job. nbsp;Edit: fixed salary raise , was a typo. nbsp;Edit 2: ok I understand I need to practice my English grammar. Im not native and Im not in US. Sorry for spelling problems. nbsp; Edit 3: The interview will be in 10 hours, so wish me luck. Thank you all for sharing your insights and tips, they were very valuable.  <response>: Hiring manager here: my current salary is none of a prospective companies business; my price to entice me to move is the only number they need.Sharing with them your salary is disproportionately advantageous to them.When asked what my current salary is, I politely explain what my I would accept to work in the roll Im interviewing in. Anyone that presses hard or blows some smoke up my ass about why they need that, then I take a hard pass on them. They know thats how it goes and they know I know why they way want to know because Im a hiring manager and my reports are hiring managers.I dont care what a previous employee was making. If I want them on my team and I am able to pay their asking I will. If I they arent in my range, I will tell them my range, and say in order to respect each others time, I cant go outside this. If you are comfortable with that range lets talk, but please be respectful of my time, if it isnt.
