As a junior, the switch job raise is much higher than that, especially if you decide to move to a larger / more active city (which is not that big of a deal as a junior). During my first job I got raised 12% over 2yearish, and swapping and moving to a larger metropolitan area brought an additional 30%-45% (depending on which offer you looked at). Now ofc there are other factor (higher life cost), but still that's massive.
