At least you get a response even if it is a rejection letter. I have heard - not experienced - that sometimes you just don't hear back from the company at all, which seems worse to me.
What was especially frustrating to me was that up to that point, the tone of both the conversations and email exchanges was very positive and cordial. I would have expected a "Thanks, but no thanks" follow-up at least, especially considering I was an internal referral from a Sr. Mgr. But... nothing. Made my reconsider my view of that particular company.
If in 2-3 weeks you haven't heard from the recruiter, you should ping them back, if no response don't was further time and move along.
Interviews often seem like hit and miss. I would recommend training at geeksforgeeks.org just to refresh dynamic programming, etc. But beyond that you're better off applying multiple places.
After 2 full days on-site with said company, I got radio silence. Not even a quick "thanks but no" email.
Of particular value are multiple reviews that corroborate certain details, especially in the absence of reviews providing contradictory details.
At the very least, with something like "ghosting" during the interview process, it can help set expectations and inform behavior such as follow-up. For example, if interview reports complain of ghosting, I might still apply, but I wouldn't exert as much (if any) effort in soliciting a post-interview reply.
(caveats re trusting glassdoor, blah blah)
It reminds me of a restaurant I worked at in my youth - because the owner and her daughter were so conflict averse - rather than fire someone, they would just slowly write them off the schedule. Sad.
Firing someone (without cause) leaves you open to having unemployment claims filed against you. Writing them off the schedule so they're forced to quit on their own accord negates that leverage; underemployment claims are harder for complainants to pursue/win.
Restaurant owners being the stingy type, I guarantee you this wasn't done to avoid hurting employee feelings.
I didn't find a useful or correct way to inform all the potential candidates about that change. That happened two times and I only sent the more generic e-mail we send for rejection telling the people that had had at least one face to face to apply for other positions if they were still interested in the company.
For the easier case of filling the headcount up with someone and not wanting the rest it's easier to send a rejection e-mail, it's just not what always happens with every job opening.
It took my friend there a week to find out that I'd been rejected.
