Pros & Cons
Cresta
- World-class engineering talent with zero politics and deep individual ownership
- Strong comp with real equity upside — median $271k TC for US engineers
- Fast-paced culture can be at odds with work-life balance during sprints
- Hyper-growth means roles and processes are constantly evolving
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
Cresta
Cresta — check Glassdoor for detailed reviews.
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.
