I know most xombots don't understand this. 25-30% increase is what you should expect when switching companies. Experienced hire to xom with several other majors under my belt. The only way to increase your base salary is to switch companies....
As soon as you hire on to a company you begin to erode your base worth because said company does not keep you on the same base salary growth curve. Those 2 and 3 percent raises don't add up to much each year. Folks working at the same company for 25_20 years are probably severely underpaid compared to what they're worth at another company.
This is normal now. You have to negotiate for the highest base and then leverage that number to your next company in 3-5 years.
