I feel like that was not that big of a deal. I mean was it a bad thing to say for multiple reasons? sure. But its still a good hour of content and no one says perfect things all the time.
There's about 2x more people on the market right now vs pre pandemic around 2019 and at least 1/3 as many positions available.
So it's at least 5 times as many applicants per position.
When you got 10 people to pass step 1, and 5 people to pass step 2, and 3 people to pass step 3, its not that hard to send a "thanks but we need someone with xyz skill".
Now, the reasons are even more random and arbitrary.
Now you might have 100 people pass step 1, and 50 people to pass step 2, and 30 people to pass step 3. So companies are pickier, but also they tend to reject you more randomly.
I've done a few interviews and they would say stuff that basically said "i'm not really listening just browsing reddit while you're talking"
