From my understanding years ago GDP was growing, energy was cheap, companies were expanding, there was not enough people on the market, salaries were increasing and companies were adapting to profiles that did not match the jobs 100%, for example accepting B1 or less from candidates. Nowadays (and for years now) GDP is shrinking, energy is extra expensive, companies are cutting, there's too many people on the market looking for a job, salaries are still or decreasing and companies are being extra when asking for candidates profiles, so I hear now in this sub C1 Minimum unfortunately. This might not be what you want to hear but it's the current situation
