The best negotiation tactic is the willingness to walk away.

State a number. Stand firm. You will have to reject a lot of offers. It's okay. Then one day, BAM, someone will be willing to match.

Malaysian banks and financial institutions are the worst. But even MNC can be really shitty. Got one German FI subsidiary, two rounds interview (until with CEO himself), I clearly stated I would want nothing less than RM6.5k. They had the balls to offer me RM5.5k. Heck even their ad said RM6k to RM9k. Reject terus. Really just buang masa.

Somehow I don’t understand what’s the purpose if jump to same position with increment of just a few hundreds but lots of uncertainty. 

Yes, i read and watched all the salary negotiation tactics out there.
Delay talks of salary until employer falls in love with you first. Stall as long as possible yada yada yada etc etc. BUT
1) that works in the Western setting where they have different laws and setting, I have yet to read a piece of advice for Asian Malaysian setting and its employment practices.
2) some company really strict. if you don't provide expected salary, they move on to someone else. Now, imagine this job candidate has a family to feed.

In cases, like this, do you STILL play this delay-salary-talks-game as long as possible or just straight reveal your expected salary?

I can only think of way to counter this move. That is, reveal your expected salary, yes BUT when employer reveals their decided salary as well, you change your mind and ask for higher. Does this work??????????
