Curious what companies these are or where you are seeing this data. This has not been what I have seen, I actually think leetcode is becoming more and more common in interviews. Just adding some of my own anecdata.
The last two companies I've worked for, and feedback I've gotten from product managers and hiring people.
All of the interviews I've done over the past few years have used leetcode, or some variant, but most of them used it only as one dimension when considering candidates. If someone was leet at coding, but bad at team work, they didn't have a chance. The opposite position was far more favorable (I've heard "you can train people to have skills, so hire for the things you can't teach" more often than once). In fact, I'm seeing companies swing the pendulum a little too far away from skills, but that's to be expected, when doing this kind of balancing.
