Correct, but it sounds like there was no option for "strongly interested in working remote part-time".

What other option is this person supposed to pick then? Saying "not at all interested" skews the results of the survey to mean that this person is not interested in remote work whatsoever.

Imo in the absence of "strongly interested in working remote part-time" answer, picking "somewhat interested in working remote full-time" is the most rational choice.
