Job interviews can make or break career opportunities, but there's a secret weapon that gives candidates a massive advantage: thorough company research using Glassdoor. With over 100 million active users and millions of employee reviews, Glassdoor has revolutionized how job seekers prepare for interviews and make informed career decisions.
What is Glassdoor?
Glassdoor is the world's most transparent career community platform. Founded in 2007 by Rich Barton, Robert Hohman, and Tim Besse, this American website allows current and former employees to anonymously review companies, share salary information, and provide interview insights. In May 2018, Recruit Holdings announced its intention to acquire Glassdoor for $1.2 billion in cash, with the acquisition completed in June 2018.
Unlike traditional job search apps, Glassdoor offers unfiltered employee perspectives on company culture, management quality, work-life balance, and compensation packages. The platform serves as both a job board and a comprehensive research tool, making it invaluable for interview preparation.
How Glassdoor Works
Glassdoor operates on a simple give-to-get model. Users contribute their own company reviews, salary reports, or interview experiences to unlock access to information about other companies. This crowdsourced approach ensures authentic, employee-generated content rather than corporate-filtered information.
The platform aggregates data across several key sections:
- Company Reviews: Anonymous employee feedback on work environment, culture, and management
- Salaries: Self-reported compensation data by job title and location
- Interviews: Candidate experiences with specific interview questions and difficulty ratings
- Jobs: Active job listings with integrated company intelligence
- Benefits: Employee-reported perks and benefit packages
Benefits of Using Glassdoor for Interview Research
Glassdoor transforms you from an uninformed candidate to a strategic interviewer. According to Glassdoor, 2 out of 3 employees say they've found a new job to be different than the expectations set during interviews. By leveraging Glassdoor's data, you can avoid this mismatch and demonstrate genuine interest in the role.
Key Advantages:
Salary Negotiation Power: Access real compensation data to negotiate confidently. The average salary for a Search is $76,322 per year in United States. Click here to see the total pay, recent salaries shared and more! This transparency helps you understand market rates before salary discussions.
Cultural Fit Assessment: According to Glassdoor research, the number one factor of company culture that matters most to a satisfied workforce is the opinion of senior leadership. Reading employee reviews helps you evaluate whether the company's values align with yours.
Interview Preparation: Candidates share specific questions they were asked, allowing you to practice relevant responses. Candidates can rate the difficulty of the interview and you can view the average rating. Some details that are available regarding interviews include the length of the process, number of interviewers, as well as specific questions that were asked.
Safety and Legality of Glassdoor Research
Using Glassdoor for interview preparation is completely legal and ethical. The platform operates transparently, and companies are aware that their information is publicly available. However, there are important considerations:
Privacy Concerns: Following a policy change in 2024 which required all users to verify their identity, real names and other personal information were automatically added to user profiles. Users should understand that anonymity isn't guaranteed.
Legal Implications: In November 2017, the U.S. Court of Appeals required disclosing Glassdoor's anonymous users' identities to prosecutors investigating possible criminal misconduct by their employers. While rare, user identities can be revealed under specific legal circumstances.
Facts vs. Fiction: Understanding Glassdoor's Reliability
Glassdoor data provides valuable insights, but users should approach it critically. Fake or forced reviews by employers can often skew a perspective on a company, and an overly negative review from one angry employee can also be misleading. Multiple reviews in a short time could be fake reviews.
Red Flags to Watch:
- Multiple similar reviews posted in quick succession
- Extremely positive or negative reviews without specific details
- Reviews that focus solely on complaints without constructive feedback
- Companies with very few reviews (less representative sample)
Verification Challenges: Glassdoor tries to verify all the user data on its platform, but they have said on their website that "we're unable to fully confirm our users' identities, the truthfulness of their contributions, or their employment status."
Employee Reviews and Testimonials
Real employee testimonials are Glassdoor's most valuable feature. Since most of the information on Glassdoor is crowdsourced and provided by current and past employees, it can give prospective employees a more in-depth look at the company – but only under certain circumstances.
When reading reviews, focus on patterns rather than individual complaints. Look for consistent themes across multiple reviews regarding management quality, work-life balance, career growth opportunities, and company culture.
Filtering for Relevance: Make sure you've filtered by location and job function: If you are interested in a company's entry-level marketing role at their Denver office, it probably won't be as helpful to look at reviews from software engineers in the company's San Francisco office.

While Glassdoor leads in company transparency, other platforms offer complementary features. Understanding where each platform excels helps you build a comprehensive research strategy.

How to Use Glassdoor Effectively
Maximize your research impact with these proven strategies:
Step 1: Company Overview Research
The first thing you are likely to see on a company's Glassdoor page is their Overview section. This will include some basic information like the company headquarters, founding date, industry, and size. Start here to understand the company's fundamental structure.
Step 2: Deep Dive into Reviews
Check out reviews for things like benefits and professional development: Glassdoor gives employees the option to comment on current benefits, so this can be a good way to learn more about potential benefits as you go through the interview process.
Step 3: Salary Research
Use salary data to understand compensation expectations and prepare for negotiation discussions. Remember that Salary packages typically include your base salary as well as additional benefits, incentives, or rewards, such as superannuation, annual and sick leave, car allowance, and bonuses.
Step 4: Interview Intelligence
The Interviews section also enables candidates to rate their interview experience as "negative," "average," or "positive." If the company provides a positive interview experience and the company reviews that you read earlier are similarly positive, you might have an overall better impression of the company.

Frequently Asked Questions
Is Glassdoor information accurate?
Glassdoor data comes directly from employees and job candidates, making it more authentic than corporate-filtered information. However, you might also learn that there's a mismatch between the interview experience and the actual job experience (perhaps one is overwhelmingly positive and the other is overwhelmingly negative), which should also factor into your decision to apply to the company.
Can employers see who views their Glassdoor page?
No, browsing company profiles is anonymous. However, contributing reviews or salary data requires account creation, and user identities can potentially be revealed under specific legal circumstances.
How recent is Glassdoor's salary data?
Salary information is continuously updated as users contribute new data. Always check the date ranges and consider multiple data points for accuracy.
Should I mention Glassdoor research in interviews?
It's generally better to reference specific knowledge about the company without explicitly mentioning Glassdoor. For example, say "I've read that your company values work-life balance" rather than "I saw on Glassdoor..."
How do I distinguish between reliable and unreliable reviews?
Look for detailed, balanced reviews that mention both positives and negatives. Perhaps you can narrow it down to what current or recent employees in the role you're applying for have to say. Avoid reviews that are extremely emotional or lack specific details.
