Please don't.

Leetcode already ruined so many coding interviews by asking people to do bullshit like

"Output data from a stream in order, make the solution performant"

Why would you ruin ML for us too?

Looking at your site, problem #1 is Multiply a matrix times a vector..... in no universe is that a legitimate ML interview question.

Also ML is such a huge field (everything from statistical learning through to transformer neural networks), I fail to see how you could say your solution tests core skills. If I'm hiring for an ASR Role, it's going to be very different than for a CV role.
