Pros & Cons
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
Twilio
- Genuine remote-first flexibility with excellent work-life balance
- Strong compensation, benefits, and engineering-driven culture
- Frequent reorgs and leadership changes create uncertainty
- Culture has shifted from creative builders to more corporate, profit-driven focus
Bottom Line
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.
