Is Your Principal Data Scientist Resume
Failing the ATS Scan?
Big Tech ATS filters reject most Principal Data Scientist resumes before a human ever reads them. We built the diagnostic rubric used by Google, Meta, and Amazon recruiters.
The Principal Data Scientist Hiring Rubric
Measurable improvements tied to model decisions: precision lift, latency reduction, or revenue attributed. 'Built ML models' without business context scores near zero.
Pipeline throughput, dataset size, and query latency. Big Tech benchmarks: trillions of events, sub-100ms SLAs, petabyte-scale processing. Volume signals seniority.
Named ML frameworks (PyTorch, TensorFlow, XGBoost), evaluation methodologies, and experiment design. Vague 'machine learning' without specifics scores low.
How model outputs connect to business outcomes — revenue, retention, engagement lift. The weakest signal on most ML resumes, and the hardest to fake.
