I guess my experience with different, because I never had to grind leetcode. I had some basic algorithmic lesson at my University (and a short adventure with competitive coding) but that's all. I never had a technical interviews where that was a problem - either there was no typical coding question, or a simple sanity check exercise. Instead we discussed some problems and thinks related to the job. I understand my experience is not typical - partially maybe I'm currently in the field of it security - but that still doesn't justify participating in the broken process with tools like this. If a company hiring process is broken just... walk away? Let them burn with leetcode grinders with no real experience that they'll finally hire.
