As a person who hires people, these interviews sound like bullshit and you shouldn't work there or feel bad about this.

My experience hiring DS/ML people is that technical skill is rarely the problem. At this point, 80% of what I am measuring is whether you are product-oriented enough to deliver something without a ton of hand holding. When the interview process is too technical-focused, you end up hiring a bunch of hermits who fail because of communication/collaboration problems or take too narrow a view on the product side.
