What is life without any risk? If the jump is >30%, try to see if you can get a counter offer from your current company. Otherwise why not take the jump.

If there is a significant pay rise to account for the risk that you are taking for making the jump, why not?

Be frank with your current line manager and then ask if there is a possibility of a counter. Of course if it doesn't go well, meaning the company doesn't offer that, ask your line manager frankly about promotion and what are the chances. Otherwise it would be another year wasted, and a lost opportunity for you. Remember, the company doesn't really owe you anything; you owe yourself to finding your own self worth.

That's a good take on things. But also, take it with a pinch of salt.

In general, people who review online are those that has a grudge to bear. I mean, you don't go and write a review on how you are enjoying your role in your current company right?

But, look out for key words and general themes as those might be an indication of how the company is. These are also questions to ask the manager during interview, the culture, the role, the expectations, and such.

My take is, you are more likely to be impacted by the manager you are under than the company you are under.

As one who managed to achieve it by being in one company, it all depends on your own initiative. No one will help you chart your path or tell you what to do. You need to know what you want to do, then work it out with your company how you want to achieve it. If you want to aim for a higher salary by being promoted, then its not about being good at your current job. You need to prove that you can already perform at the next level. Document all of your achievements, all of your discussions and target with your line manager/supervisor. Make sure that you yourself chart out a career path you want to achieve and then find validation whether that is achievable internally whether again it is with your supervisor/line manager/HR. If all things seem unlikely, then start building up your personal portfolio of achievements and find out what roles you want to apply for outside. Don't use whatever you have now at your current workplace in terms of achievement because all that shows is that you are just performing at your current level. If the role you want out there is a management role, then start finding as many opportunities to show that your initiative and effort in trying to build your skills in that area. For example, if you dont have a chance to say lead a team at your current role, find out initiatives within your company where you can be the lead (e.g. such as leading a team building event or leading a new initiative).

If you just think of a 5% annual increment, you will wait forever before you reach a RM10k salary.
