Glassdoor is not reliable. Companies can pay to suppress negative comments.
Are there trusted impartial review sites?
They exist, but are very few - their articles get stolen by unscrupulous copycats, or the AI slop buries them in noise. It’s like panning for gold, but instead of a bubbling creek it’s sewage runoff. I hardly ever find trustworthy results on the first page any more, you got to go several pages deep until you stop seeing the “Top N <search term> you absolutely need to buy!” results.
Well that looks like a tick, so it wasn’t a spider.
Also, reminds me of a classic story: https://quirogatranslated.wordpress.com/2014/06/20/the-feather-pillow/
