When you shift jobs after two years of experience, it is the perfect opportunity for asking for a major promotion. Yes, I did it; in my initial offer, I requested a 50% increase, but they only offered 40%. That is sufficient for me to drop material and enter the honeymoon period (notice period). Later that, I received three additional offers, the largest of which provided me with a 70% raise, therefore now is the moment for you to receive a 50-70% hike. Because after 5-6 years, you should not be considering hike much, rather about safety and a stress-free use.
