Yes, it is certainly possible if you follow the tips below, but dont expect a good/comfortable life or even have much savings

1. I am not sure why people buy a car with RM 2500 starting pay, how can they afford the down payment?
2. Have to go out of the way to eat cheap food (mixed rice/cheap breakfast), no expensive food.
3. Not much entertainment.
4. Maybe share room rental/or rent cheap outskirt area
5. Do some partime on weekends?
6. No savings

The point is NOT to stay at RM 2,500 for long, its a starting pay, and should increase quite fast. After 6 mths probation, you can maybe have some increment, and after that increment/adjustment/promotion etc all will increase your pay.

If you are stuck at RM 2,500 for too long and cannot afford good life/support family/have gf, maybe its your attitude problem?

For short term, 2500 isnt a problem, but for long term its certainly quite impossible.

See got 1 poster above jump from 1.8k to 4.5k within 2 years.

In MNC you got to fight for your chance to perform. If you everything also tell boss cannot/dunknow obviously you will be kept diam2 inside cubicle. Show some initiative, learn from different dep, talk to different boss, take professional paper eg. IT cert/acca, dont complain when OT or do job outside job scope. Try to get 1st promotion within 2-3 years, then jump company once u get promotion (thats almost 50-75% payrise within 3 years to about 4k. And thats quite conservative expectation that is doable for most people.

Or you can be life insurance/property or car salesman and earn even more. (but obviously sales is harder)

It is quite simple to rise in pay quickly if you are hardworking, willing to put in effort. Wont stay at 2.5k for long so why worry?
