I got a few interviews and the recruiters used special web-apps for the process and even then they didn't think about getting back and tell me it's done.
And why should they? They get paid for good hires, not for telling the bad ones they aren't needed.
We probably need more comments like the one of devnull42 to raise awareness.
This wasn't "not telling the bad one that wasn't needed" -- it was "reviewer (who is our engineering manager for that department) liked him, and put notes to that effect in his file, and the next step is supposed to be in-house recruiter following up to do the next interviews". The in-house recruiter didn't get the note, and there was no internal feedback loop to say it had been stalled. We actually hired a (great) engineer on the data team after he followed up on a post like this months ago; I'm aware the process is broken, and we're trying to improve it.)
We use jobscore. I really wish we used lever.co to track this stuff instead.
On the teams where I am more involved in hiring (i.e. not SRE), we separately track candidates after initial screening using Jira (which we use for everything else), so people don't get dropped.
