> Fast students are smarter.

Dubious assertion.

> "smarter" here means how well the student will perform in a career in their chosen field. Fast + accurate is the ideal.

Still dubious.

Also, I don't know where you work, but in most of my jobs, career growth is not limited by speed with which you do the work. It's one factor among, say, 10. Most of the people who got ahead were not the fastest.

They're not trying to gauge who is the fastest. Or even the smartest. Just those who have the skills. In the real world, you'll rarely (as in, never) have to solve those same problems with the same speed you will in the exam.

In a lot (all?) of the jobs I worked, taking a day to solve a Medium level Leetcode problem was quite OK.
