I’ve worked for quite a few companies that have been circling the drain, and have done a lot of hiring, placement, and career transition work over the last couple decades.
Failing companies often still hire to keep the lights on, and people who are desperate for a particular job in a particular space often still take those jobs so they can get anything on their resume (design, marketing, etc can’t be hard to break into professionally, but be rewarding once you get a foot in the door).
As for the training thing, that’s not always a great option for a lot of spaces. You might go from a job that you climbed, and pays your mortgage and feeds your kids, to starting at the bottom all over. People in that position will often try to hold out and spend extra energy on a job hunt and interviewing, because the alternative can be a pretty big impact to financial stability.
