While I cannot redistribute the PDF here (please support the author if he releases an official edition), I can share the structural insights that make it the "better" choice.
Is the PDF perfect? No. Critics note that the original version lacks deep dives into cost calculation (e.g., $ per 1K predictions on AWS vs. GCP) and can be light on modern orchestration tools like Flyte or Ray. Furthermore, because it is a self-published PDF, the visual diagrams are sometimes less polished than those in a retail book.
However, for the majority of senior-level interviews, the signal-to-noise ratio of Aminian’s material is unmatched. It is not a beginner’s guide to Python or a stats refresher. It assumes you know the basics and cuts straight to the system design case studies.
Most guides start with the infrastructure (Kubernetes, Kafka). Aminian starts with the data. He forces you to ask:
By anchoring the design in the statistical properties of the data, the architecture becomes an emergent property of the problem, not a pre-baked template.
| Resource | Strength | Weakness | |----------|----------|----------| | Ali Aminian (PDF) | ML-specific frameworks, concise, interview-focused | Less detail on pure infrastructure (e.g., Kubernetes) | | Alex Xu – Vol 2 (ML chapter) | Great diagrams, general system design context | ML depth is limited to a few chapters | | Chip Huyen – Designing ML Systems | Deep, principled, production-focused | Too detailed for interview prep (more for builders) | | Grokking ML System Design (Educative) | Interactive, structured | Paywall, sometimes outdated | | Google’s ML System Design (public guide) | Official, high-level | Not enough for live coding/whiteboard |
Verdict: Aminian is better for the fast-paced interview format where you need to cover end-to-end in 45 minutes.

If you have browsed Reddit’s r/cscareerquestions or r/mlops recently, you have probably seen the whisper network recommending one specific resource: Ali Aminian’s Machine Learning System Design Interview PDF.
Let’s be honest. The market is flooded with ML system design content. You have the "Blue Book" (Alex Xu), Grokking the ML Interview (Educative), and countless GitHub repos. So, why is a single PDF from a Senior ML Engineer at Google DeepMind causing such a stir?
Because it fixes what is broken about most prep guides. Here is the honest breakdown of why this PDF deserves a permanent spot on your desktop.
If you're preparing for machine learning system design interviews, here are several resources that might help:
