Google Interview Questions & Trends 2026 Q2: OA, VO, Coding & Behavioral
Overall Trend
Google continues large-scale NG / Early Career hiring in 2026 Q2, with L4 SWE and AI/ML tracks dominating the pipeline. Several teams (Search/Ads/Recsys, AI/ML Infra, Cloud AI, MLE Recsys) have standardized on a "BQ + ML Domain + 2 Coding" four-round structure. Coding difficulty stays at LC medium, but follow-ups now consistently demand complexity optimization, scalability reasoning, and proactive edge-case coverage — communication quality and "pushing toward the optimal solution" matter almost as much as AC.

Difficulty Trend
Coding difficulty stays at LC medium overall, but follow-up "depth ramping" is noticeably faster than the previous quarter — many interviewers no longer settle for AC and immediately push for space optimization, streaming/distributed processing, and concurrency control.
