It is definitely true in my experience, and for those seeking 100% remote or with only 0-3 years of real experience (not school) it is even worse.
I have posted this comment before on HN, but ~8-9 months ago we posted a job for a lead engineer at my company - we got 3 applicants (this was for a fortune 50 company, and comp, while not FAANG, was very respectable with good benefits and decent bonus and stock options to boot).
~5-6 months after that we added another exact same position, and advertised it in the exact same places and got over 300 applicants - many ex-FAANG which we never used to get.
So based on my personal experience, there are a lot more people looking and applying for jobs and a lot less jobs to choose from - and like I said, if you are dead-set on being remote, it is even harder - my most recent employer (100k+ employees) will no longer allow hiring managers to interview people who state they are only looking for remote (they don't have to, plenty of people are willing to show up at the office because they have rent/mortgage and bills to pay).
