Really solid breakdown. I like how you actually tied each one back to what it’s good for in real interviews. That’s where most guides miss the mark. The distinction between “learning tools vs interview simulation tools” is especially helpful because people often mix them up and end up feeling stuck.

Glad that resonated with you. That distinction is honestly where a lot of people get stuck without realizing it.
I’ve seen the same thing happen a lot: people stack too many “learning” tools and still feel unprepared for actual interviews.
