Google India Senior MLE / Research Scientist Interview Guide
Google India (Bangalore + Hyderabad + Gurgaon) hires senior MLE / Research Scientist roles across Search, Ads, Maps, YouTube, Cloud AI, DeepMind India, and Android. The interview is the deepest of any company — coding, ML, system design, research depth all probed rigorously. This guide covers it.
Google India houses senior ML hiring across Search, Ads (one of the largest ML operations globally), Maps, YouTube, Cloud AI / Vertex, DeepMind India (research), and Android ML. Roles include Senior SWE-ML (L5/L6), Senior Research Scientist (research), and AI Resident-to-FTE. The interview is the deepest in industry.
The loop structure (Senior SWE-ML / RS)
Standard Google loop: phone screen (coding) → on-site 4-5 rounds.
Round-by-round breakdown
Phone screen. 45 min coding (1 problem). High bar.
On-site rounds.
Bar. Highest in industry. Even seniors fail for surface answers. Hire/no-hire votes by committee, not just team.
What Google India weights distinctively
1. Coding depth. LeetCode hard is the standard. 2. System design at planetary scale. Search-quality, YouTube ranking, Ads auctions. 3. Research fluency. For research roles, deep math derivations expected. 4. Googleyness. Collaborative, mission-driven, non-political culture.
Top 10 questions
1. "Design YouTube recommendations end-to-end." 2. "Design Google Search ranking. What's the ML stack?" 3. "Code: efficient implementation of a candidate generator using ANN." 4. "Code: hard graph problem." 5. "Derive backpropagation for a specific architecture." 6. "Ads auction theory — pCTR calibration importance." 7. "Walk through a recent paper that influenced you." 8. "Most impactful project — with depth." 9. "Conflict resolution — recent example." 10. "Why Google?"
