I’m not sure what “entry level” means here, but ‘data scientist’ is not an entry level job.
Yes, data scientist is an entry level job title. Seniority is defined by an assigned level of experience (I, II, III, etc).
The rest of the story is that the jobs with 6 figure salaries are located where the cost of living is so high that tech companies are forced to pay these wages just to have a workforce. An entry level data scientist who prefers to live in the Midwest will start at half that salary, but will have a better standard of living, have short commutes to work, and can actually afford to buy a home.
