You have found a role that looks right, and before you spend an evening on the application you open Glassdoor, Indeed or a similar site and type in the employer's name. Three and a half stars, a furious post from last month, a string of cheerful five-star ones. Now what? Employee reviews are worth reading before you apply, as long as you treat them as a screening tool and not as a verdict.
Who writes a review, and when
Almost nobody writes a review on an ordinary Tuesday in their third year at a company where things are fine. People write at moments of strong feeling, and there are two obvious ones: the week they leave and the months just after they arrive.
The angry leaver has a real story and a narrow view of it. They were passed over, managed out or made redundant, and the review is written while it still stings. That does not make it false. It does mean the tone is hotter than the average experience, and that one bad manager can colour the description of a whole company.
The freshly hired are the mirror image. Everything is new, the onboarding was friendly, and nobody has moved their holiday yet. Some employers also encourage new joiners to post, which is not sinister but does tilt the sample. A review that praises "great culture" after eight weeks tells you the welcome is good. It says little about year two.
The group you rarely hear from is the content middle: people who have been there a while, like it well enough, and have no reason to tell the internet. So the star rating is an average of the extremes. I would not ignore it, but I would not let half a star decide anything either.
Patterns beat single posts
One review is an anecdote. The useful thing is repetition across people who do not sound alike.
Read fifteen or twenty posts quickly and write down every specific complaint and every specific compliment. Not "toxic" or "amazing", which carry no information, but things you could check: unpaid overtime before quarter end, promotions that go to external hires, a training budget people really use, messages from the boss at eleven at night. Then count. A complaint that appears once is one person's bad year. The same complaint from six people in different roles, in different words, is probably how the place works.
Pay attention to what the positive reviews concede. When someone who gives five stars writes "pay is below market, but the team is great", and the one-star reviews also mention pay, you have found something solid. Agreement between people who disagree about everything else is the strongest evidence a review page can give you.
Check the date, then check what changed
A review describes the company on the day it was written. Sort by most recent and look at where the complaints sit in time. A wave of bitter posts from three years ago, followed by quieter and more mixed ones, suggests something was fixed, or that the people responsible left.
Then spend two minutes on what has happened since. A new chief executive, an acquisition, a round of layoffs, a return-to-office order: each of these resets what older reviews are worth. Layoffs in particular produce a burst of angry posts that tell you about the layoff and not much about the daily job of the people who stayed. If the same complaint runs straight through a change of management, though, it has outlived its excuse.
Match the reviewer to the job you want
A large employer is not one workplace. Most sites show a job title, a location and sometimes a length of service, and many let you filter on them. Those options differ from site to site and change over time, as do moderation rules, so use whatever is there on the day you look. Three things matter:
- Department. Sales and engineering inside one employer often live under different targets, managers and hours.
- Location. A branch or regional office has its own boss. Give more weight to reviews from the site where you would work.
- Seniority. "No progression" from someone who stayed nine months means less than the same line from someone who stayed five years.
Employer replies and suspicious clusters
Some employers reply to reviews, and the replies are often more revealing than the reviews. A reply that names the issue, says what was done about it and offers a contact shows an employer that can hear criticism. A reply that argues, hints at who the reviewer is, or explains that they were a poor performer shows you how disagreement is handled internally. And the identical paragraph pasted under forty reviews tells you nobody read any of them. No replies at all is neutral; plenty of decent employers simply do not engage.
Then look at the shape of the praise. I cannot tell you which reviews on any site are genuine, and nobody can from the outside. What you can notice is a cluster: a dozen five-star posts within a few days, each two lines long, all using the same handful of phrases, none mentioning a team, a project or a single drawback. Real praise tends to be specific and slightly uneven. When a cluster like that appears right after a run of harsh reviews, I give it little weight. That is not an accusation, only a decision about how much short, uniform posts deserve, and it applies just as well to five vicious posts with identical wording.
What reviews cannot tell you
Here is the limit. The biggest factor in whether you like a job is the person you report to, and reviews almost never tell you who that will be. Your future manager may have joined last month.
So reviews should rarely stop you applying. An application costs an hour or two, less if your CV is already in shape (a tool like Postulit builds one from your LinkedIn profile), and it buys you the right to find out in person. I would only walk away at this stage when the same serious complaint, such as late pay or bullying that management tolerates, comes up again and again in recent reviews from your own department.
Turn the complaint into a question
For everything short of that, convert the pattern into a question and carry it into the process. Never quote the review; it puts the interviewer on the defensive and teaches you nothing. Ask about the fact underneath.
- Recurring complaint about hours: "What does a normal week look like in this team in the last month of a quarter?"
- Recurring complaint about turnover: "How long have the people in this team been here?"
- Recurring complaint about promotion: "Who was the last person promoted from this role, and into what?"
A straight answer suggests the reviews are out of date or never applied to this team. A vague one confirms them. Our articles on smart questions about company culture and on interview red flags from the company take it from there.
A fifteen-minute routine per employer
Set a timer. Without one, reading reviews becomes an hour of scrolling that leaves you more anxious and no better informed.
- Minutes 1 to 3. Note the overall rating and the number of reviews, then sort by newest.
- Minutes 3 to 8. Skim the twenty most recent posts and tally specific complaints and specific praise.
- Minutes 8 to 10. Filter for your department, location and level. Mark which items survive.
- Minutes 10 to 12. Read three or four employer replies and sum up the tone in one word.
- Minutes 12 to 14. Look for a recent change: new leadership, layoffs, a merger. Cross out complaints that clearly predate it.
- Minute 15. Write down two questions for later and one sentence: apply, apply with caution, or skip.
Reviews tell you what to ask, not what to conclude.
Keep the note with your application. If you reach an interview, those two questions are already written, and you will be putting them to the one person the reviews could not describe.
