Deep-dive your recent project architecture

Q: Deep-dive your recent project architecture

This question evaluates a candidate's ability to describe end-to-end system architecture, justify design decisions and trade-offs, and demonstrate competencies in data modeling, storage strategies, deployment topology, scalability, consistency models, observability, and incident management.

Q: How do I approach System Design interview questions?

System Design questions require understanding of core concepts and practice. PracHub provides solutions with explanations to help you master system design interviews.

Question

End-to-End Project Architecture Walkthrough (Technical System Design)

Provide a structured walkthrough of a recent system you built or led. Cover both the "what" (architecture) and the "why" (design decisions and trade-offs).

What to Include

System overview and goals
Core components and end-to-end data flow
Data model and storage strategy
External dependencies (e.g., queues, caches, databases, third-party services)
Deployment topology (regions/AZs, containers/VMs, autoscaling, networking)
Key design decisions, trade-offs, and constraints (latency, throughput, cost)
Failure modes you encountered, how you detected them, and mitigations
What you would redesign if you had another iteration
Concrete metrics and incidents (latency percentiles, QPS, error rates, costs, outcomes)

Be specific about SLIs/SLOs, budgets for latency, partitioning/sharding, consistency model, and how you validated impact (A/B testing, canaries, rollbacks).
