Looks like LeetCode is for technical/coding questions. Whereas, Interview School is for non-technical questions like behavioral questions. So, instead of solving coding questions, we are presenting you with a questions like "Where do you see yourself in 5 years?", in which you would then answer while being recorded. We then run it through some Watson APIs so that we could give you some grading based on your tone, confidence, and the number of filler words you used. So you can practice on that aspect of your interview. We also take questions that have already been reported from that specific question and company.
