Employers' recruitment is not based on the number of units you have worked in, but on the length of time you have worked in a unit, which can explain a person's loyalty to the enterprise. If you jump six companies a year, then this person must be "this person lacks perseverance, cares too much about personal gains and losses, and changes jobs too often, so it is not available."

If you danced six times in 10, I don't think it matters at all, do you?

As for work ability, the employer will not consider it from the perspective of job-hopping, but from your professional background, work content, grades, interview and so on. There is no absolute correlation between the two.
