I’m job hunting right now and turning over a lot of similar questions, about how much I should be asking for.

A few years back I got over 80% by switching sectors - I was underpaid at a public sector job I loved, and switched to a private sector job in the finance industry and a higher COL area. Similar to you, they offered more than I asked for because corporate had specific pay brackets for that position.

I think your pay depends a lot on the specific area/tech stack you’re working in and who you’re working for. Some tech stacks just pay more on average than others, bigger corporations can usually pay more than smaller companies, and private sector will always pay more than public sector (but usually with worse benefits). You can check Glassdoor or similar sites to see what people with a similar title make at the company you’re applying to, but that’s only helpful at really big companies where there are enough employees reporting to give a good average.
