Archletics

Archletics is a drill book for system design. Not videos, not another course to fall behind on — 308 questions you actually answer, with written feedback on every one. Ten modules cover the ground interviews keep coming back to: fundamentals, caching, databases, replication, sharding, queues, rate limiting, storage and CDN, capacity, and observability. Six full design problems then put the pieces together end to end. TEN KINDS OF DRILL, NOT TEN OF THE SAME Multiple choice is the easy part. Archletics also asks you to assemble an architecture from its components, find the bottleneck in a design, put a sequence of operations in order, estimate capacity from first principles, match concepts to the jobs they do, fill in a comparison matrix, triage an incident, classify a workload — and write free-text answers that get read and graded. FEEDBACK, NOT JUST A SCORE Every answer you type comes back marked, with the reasoning spelled out. You find out which part you got wrong and why, rather than just that you missed it. SEE WHAT YOU ACTUALLY KNOW Accuracy per module, your practice sessions, and a path through the material that reflects what you have and have not covered. Ten written explainers fill in the theory when a drill catches you out. Archletics is for engineers preparing for a system design interview, and for anyone who would rather stop nodding along to architecture diagrams. ARCHLETICS PRO Grading is the paid part.
