Reviews on Glassdoor can be fake or they can be honest and reliable. It can be difficult to tell the difference. Glassdoor does not verify employment and users can open multiple accounts in order to post a number of reviews (until they’re caught). And even valid reviews are highly subjective. Reviews may only apply to one department, they may be outdated or employees may be compensated to log positive reviews. Disgruntled current and former employees tend to exaggerate and people are 21% more likely to write negative reviews than positive ones, and you could say that Glassdoor reviews might not be reliable, even if they are real.
