• Salary Research: Benchmark against 190 countries' data; verify with ranges for your title/location.
• Red Flags: Low work-life balance (declining even in hybrid setups), CEO scores >90% but <50% recommend % = poor management.
• CEO Ratings: High like Bain's 99% predict stability; analyze gaps in tech (90% approval vs. 80% outlook).
• Recommend % Interpretation: 50% threshold indicates dysfunction--cross-check with diversity ratings (19% revenue boost for strong DEI).
• 2026 Trends: 24% rise in leadership "disconnect," rolling "forever layoffs," 12% fewer offer rejections--prioritize hybrid WLB ratings.

Understanding Glassdoor Rating Metrics: What Every Job Seeker Must Know

Glassdoor's 5-point scale (1=very dissatisfied, 5=very satisfied) powers insights trusted by millions. Overall ratings correlate to +6% stock growth for high scorers vs. <1% for low ones. Compare across industries: consulting (Bain 99% CEO) outperforms tech amid layoffs.

Nearly 80% of CEOs rank culture as a top valuation driver--use these metrics to assess fit.

How to Interpret "Recommend to a Friend" and CEO Approval Ratings

"Recommend to a Friend" below 50% flags poor management, per analysis of tech firms where CEOs score 90%+ approval but outlook lags. Bain's Bob Bechek hit 99% in past rankings; NVIDIA leads 2025. Contradictory data? High CEO (e.g., 90%) with 80% outlook gaps signals instability--seen in 24% more "disconnect" mentions.

Work-Life Balance, Diversity, and Benefits Breakdown
