This is no different than doctors who have to go through FRCS or EDAIC etc exams, these are very hard exams with very low pass percentage adding to the fact that you need to be a qualified MD when you give these exams. my wife is an MD and has been giving exams for the past 3 years and will be giving exams for atleast another 3 to 4 years and she studies with whatever little time she has after work. The exams she gives have little to nothing to do with the work she does. The real life medical work does not require you to be smart, most average people could do surgeries if they are trained. But getting in is the hard part. The exams there are not qualifying rounds but elimination rounds. Medicine is an old field, and I think these leetcode style interviews are only the beginning for the computer science based industry, the bar is only going to get higher as years pass which I feel may not be a bad thing overall for the software field.
