I was discussing an unrelated issue on Discord and I shared links to 2 similar searches.
After sharing, I double-checked my links on non-logged-in browser to verify others would see the same results, and I discovered that the results are not infact the same.
Here are the links:

On my side the top results are 'quora.com' and 'cclgroup.com' respectively. But when viewed by others, the top result for both searches is 'exchange-rates.org'. I do no thave exchanges-rates.org blocked or down-ranked.
I was able to confirm another user on the discord channel was also receiving different results when viewing the links.
My results:

Results from another user after they followed the links I shared:

I would expect the results from a shared search results page to appear exactly the same when viewed by another user.
(*edit: not sure if it's relevant, but the exchange-rates.org results seems like it might come from the Bing index, it doesn't appear on Google at all, but tops the result on Bing.com)
