maybe they realized hiring leetcode junkies is not a great strategy and they want to freeze that while they find a better interview system
It’s a way to filter out more experienced candidates because they want cheap and young. Even a Meta recruiter admits to me that Leetcode has nothing to do with the job, it’s just a company requirement that no one questions.
They could easily pay 30% less and still fill their positions if they just lowered the bar to get hired.
