Actual work experience, presumably in whatever you want them to be experienced in. E.g. If a job requires you to use Java then you’d need work experience in Java. Things that are very similar may also qualify. E.g. Someone knows JS and job requires TS.
But maybe I’m misunderstanding the question. If we’re talking more like what makes a developer a senior developer then it’s completely different criteria.
Im keeping this open to be honest. I agree, there is a difference between Experienced and Senior Software Developers. One does not equal the other necessarily.
