About a year ago, I sent out over a hundred resumes, got 3 callbacks, most of which weren't serious, and then there was one job I wrote a cover letter for because I matched everything they were looking for and handily got the job.

So it's both impossible and very very easy.

I think tech hiring is going to be a knife fight for a long time, because we're long past the point where only the thoroughly interested are looking for jobs in this industry, and there's so much money in the field that competition is high enough for people to take "towers of hanoi in optimized big o" interview tests seriously (probably because they cut the candidate field down to a manageable number)

>For those that have gone remote, any specific insights?

Be ready to manage your time, it's very easy to let 15 minutes off for chores turn into blowing off a whole day.
