Likely format

Google SWE loop: phone screen(s) covering coding and ML/infra domain knowledge, followed by onsite rounds spanning coding, ML system design, and Googleyness/leadership behavioral interviews.

What this interview tests

  • ML model design for fault prediction/anomaly detection at fleet scale
  • Working with large-scale telemetry and operational data pipelines
  • ML infrastructure: model deployment, evaluation, fine-tuning, debugging
  • Cross-functional partnership with hardware designers and SREs
  • Technical leadership: setting direction, translating findings for executives

Common question themes

Design an ML system to predict hardware faults from fleet telemetry data

How do you evaluate a model when failure events are rare/imbalanced

Describe a project applying ML to an infrastructure reliability problem

How do you productionize and monitor an ML model that others depend on operationally

Explain a complex technical reliability finding to a non-technical stakeholder
