Thing is: Majority of failed interviews can be probably traced back to a relatively small pool of mediocre engineers, who get rejected by dozens of companies, before they finaly land a job. And then they loose that job 3-12 months later, because they coulndn't keep up with their employer expectations. So, at least in theory, both "there's talent shortage" and "it is so hard to land a job" can be true at the same time, just for different groups of people.
