It's normal for a company to hire a the highest skilled person they can get with the lowest pay possible so they can increase their ROI.

A good company will not offer you much as they are doing good.

A 'going-downwards' company will offer you much more to get things good (and risk of being fired / retrenched if you don't do good!).

All of these, will eventually fall back to you. If you don't really need the job and looking for more MONEY, then you can tell them that you have surveyed the market, and found that your expected salary is what they should expect to get people to do the job - but of course, be logical and don't expect a RM10k pay for a RM3k job.

If you are desperate (I know not all will agree to this), you might want to turn around the table and ask 'How much does an average XXXXXX earn at your company?' And you can go further there by your own to decide if you should sell yourself off for that price or not.
