Bottom Line
Harvey
Choose Harvey if you want exceptional equity, smart colleagues, and the chance to reshape the legal industry with AI — but expect relentless pace, long hours, and growing-company politics.
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.
