I think the unstated part of the parent comment is that the zoom meetings aren't being scheduled in one block of time like in person meetings would be, but spread out over multiple days.

For some people, it's easier to take 1 day off work to go do a series of interviews than to fit 5 different one-hour interviews at different times over the course of a week.

If the company scheduled the zoom calls all in one block, then ya, zoom would still be more convenient than in person.
