How Accurate Are Levels.fyi and Blind Data?
The accuracy of Levels.fyi and Blind data varies. A 2022 survey found that 60% of tech professionals reported salary discrepancies between online data and their actual offers. Not the data points, but the context matters. For instance, a product manager at Google might see a reported salary range of $150,000 - $200,000, but the actual offer might depend on factors like experience, location, and performance.
Can I Rely on Levels.fyi and Blind for Negotiation?
No, you shouldn't rely solely on Levels.fyi and Blind for negotiation. These sources provide a starting point, but not the entire story. A more effective approach involves researching company-specific data, networking with professionals in similar roles, and understanding the company's budget and priorities. It's not about having the highest salary data, but about understanding the company's constraints and opportunities.

How Do I Verify the Accuracy of Online Salary Data?
Verifying online salary data requires a multi-step approach. First, cross-check data points across multiple sources. Second, network with professionals in similar roles to gather anecdotal evidence. Third, research company-specific data, such as Glassdoor or LinkedIn salary reports. Not verification, but triangulation is key. By considering multiple sources and factors, you can develop a more accurate understanding of salary ranges.
What Are the Limitations of Levels.fyi and Blind Data?
The limitations of Levels.fyi and Blind data include small sample sizes, self-reported data, and lack of context. For example, a product manager at Facebook might report a salary of $180,000, but without knowing their experience, location, or performance, it's difficult to accurately gauge the relevance of that data point. Not the data, but the story behind it matters.
