Have a calm discussion with them, make it in-depth technical but also talk to them in a friendly manner. No need for take-home tests or leetcodes, and no need to be a robot also. Why can't it be as simple as that?
I'm 6 years into this "career" (more like a job than a career but anyway) and now I'm coding probably 4 hours per day. It wasn't that different in the beginning though.
A person that loves this one must be a total degenerate, and it looks like IQ doesn't correlate with that.
Intelligence is a broader term, of course there are no such tests, only IQ ones... which is to say, i was kind of kidding. But I do despise this culture of total degeneracy nevertheless.
I've spent about 2 years cumulatively doing absolutely nothing at "work".
There was a funny case where I was assigned to a project that had almost no work and no meetings at all. And in another case I was in a dev support team as a junior, where we had meetings but it didn't matter at all what we were reporting, nobody cared if it took you two months or more for a simple bug.
