Is it hard to switch after 10 years?
It is slower rather than harder. Fewer roles exist at this level and loops involve more stakeholders. Across all 14 verified switches HikeCatalyst has documented, the median was 4 offers and 11 weeks to close โ plan the search as a project rather than a weekend of applications.
Does a 10-year resume need every project?
No. Depth on recent, relevant work beats completeness. Anything more than five or six years old belongs in one or two summarising lines unless it directly supports the role you are targeting.
Will an older technology stack count against me?
Only if your resume makes the stack the point. Lead with the problems solved โ scale, reliability, migration, cost, data correctness โ and the specific technology becomes a detail rather than a filter.
Should I take a title cut to join a better company?
Sometimes, but be precise about what you are buying. A title cut with a genuine scope increase can pay back quickly; a title cut with the same scope is a downgrade with better branding.
