I recently turned down a job offer exactly because the company's HR just added 20% on top of my current pay. I questioned her back by asking her if I'm underpaid in my current job that means I'll be underpaid when I accept their job offer. The HR just kept quiet after that.

Seriously, do a survey on the market price before you accept any job offers; I have some colleagues earning less than RM3k with 5 years working experience in relevant field.

Haha bingo, I answered the same set of questions before

"If you think you are underpaid, why are you accepting the job offer for your current job at first place? "
- Its my first job, gaining experience is far more important than the figure printed on my payslip. I know the market price for the position I'm applying for and I know my qualifications very well.

To be frank, I was earning RM2k previously. I wrote RM3.2k as my expected salary for the job offer and the HR called up and told me I'm expecting waaay too much. I attended the interview, and with my experience I manage to bargain from RM2.5k up to close to RM3k.

(1st job) RM2000 -> (2nd job) RM2800+; too bad I have higher offers that does not bother how much I earn on my previous job. To answer you, RM2000 + 20% is still severely underpaid if you ask me.

The HR called and told me I'm requesting too much, but its the project manager who interviewed me and he was the one who thinks that I do deserve the pay I'm requesting for. In the end it is still up to how well you sell yourself, and how close does your working experience matches their needs. For me, I know what cards I have on my deck and I'd played them well.

p.s. I don't even have to fake my payslip But to be frank I never like to talk to HR people
