Pros & Cons
Google DeepMind

- Google-level compensation and benefits with genuine work-life balance
- Google-scale bureaucracy — slow decision-making compared to startups
- Large org means less individual ownership and impact on direction
Perplexity AI

- Startup intensity — expect long hours and high expectations
- Growing pains as the team scales — roles and responsibilities shift frequently
Bottom Line
Google DeepMind
Brilliant research environment with strong work-life balance and excellent pay — but Google-scale bureaucracy and post-merger politics slow things down.
Perplexity AI
Choose Perplexity if you want the fastest-growing AI product and huge per-engineer impact — but expect startup intensity.
