It's not an interview if they're paying you, it's a conditional hire for a week. Calling it an interview is like calling actually starting a job after a barrage of three interviews the fourth interview. At some point you're torturing the meaning of the word to pointlessness.
If the tasks you're doing that week are purely for assessment purposes and the environment is completely different from the actual work place (as it takes place remotely), I'd say it's closer to a paid interview, which isn't new, than a classic trial period. It isn't that much longer than the process of some big companies, if you add all the interviews together.
I certainly understand people who think otherwise though.
