I get why companies don't do honest rejection letters, but this there's no excuse for whatsoever.
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)
