Pros & Cons
Glean
- World-class AI talent — learn from ex-Google leadership on cutting-edge enterprise search
- Transparent collaborative culture with strong career growth
- Below-market compensation — comp rated only 3.6/5
- Sales org has high churn and toxicity problems in EMEA and US
Mercor
- Massive impact at an AI company growing at breakneck speed
- Top-tier compensation with strong equity at $10B valuation
- Intense 9/9/6 work schedule — long hours are the norm
- Work-life balance is a real sacrifice at this stage
Bottom Line
Glean
Top-tier AI engineering talent and explosive growth, but comp lags peers and the sales org has churn problems — the engineering side is the real draw.
Mercor
Choose Mercor if you want outsized impact on AI-era hiring at a tiny, fast-moving team — but the 9/9/6 schedule is real, and work-life balance is genuinely sacrificed for speed.
