Practice System Design.
Not Just Study It.
ArchWyse puts you inside a realistic mock interview — AI interviewer, voice interaction, and an interactive whiteboard. Speak your architecture decisions, defend them under follow-up questioning, and build the skill you actually need.
"AI can already write code. But it can't yet design systems that scale."
That's your competitive edge in every senior interview. But you don't build architectural thinking by reading about it — you build it by defending decisions live, under pressure. That's what ArchWyse simulates.
Technical Depth
Go beyond surface-level answers. Practice defending component choices — when to use a cache, which database fits, how to handle queue backpressure — to an AI that asks why until your reasoning holds up.
Systems Thinking
Articulate the whole system in real time. Practice reasoning through component interactions, scaling bottlenecks, and failure modes — out loud, under interview conditions, with an AI that probes every gap.
Clear Communication
Interviews aren't just technical. Use voice interaction to practice narrating your thought process, handling live clarifying questions, and presenting trade-offs with confidence — before the real thing.
How a session works
Four steps from blank canvas to expert-level feedback in under an hour.
Pick a Problem
Choose from 50+ real-world interview problems — design Twitter, Netflix, Uber, a URL shortener, and more. Difficulty calibrates to your experience level.
Draw & Explain
Use the Excalidraw whiteboard and your voice to draw your architecture and talk through every decision as you would in a real interview.
AI Interviews You
ARIA — our Adaptive Real-time Interview Advisor — acts as your interviewer, asking clarifying questions, probing edge cases, and challenging your assumptions in real time.
Get Deep Feedback
Receive a scored evaluation across scalability, reliability, trade-offs, and communication quality with specific improvement notes.
Everything you need to nail it
Built for engineers who want to practice interviews, not just study theory. Every feature simulates the real thing.
Excalidraw Whiteboard
A full Excalidraw canvas embedded in your session. Draw boxes, arrows, labels — whatever your architecture needs. The AI reads your diagram in real-time.
Voice Interaction
Speak your design decisions just like a real interview. Whisper transcription captures every word accurately, even technical terms like "Cassandra" or "consistent hashing."
ARIA — Your AI Interviewer
ARIA (Adaptive Real-time Interview Advisor) asks follow-up questions, challenges your assumptions, and keeps you on track — just like a real senior engineer would in a loop interview.
Scored Evaluation
Post-session rubric scoring across scalability, reliability, trade-offs, feasibility, and communication quality.
Diagram Analysis
Submit your whiteboard to the AI and get immediate analysis — missing components, anti-patterns, and specific improvement suggestions.
Experience-Level Calibration
Every mock interview adapts to your level. Whether you're a fresher tackling your first HLD interview or a staff engineer defending trade-offs at scale, the AI calibrates its expectations, follow-up depth, and scoring rubric accordingly.
Built by engineers
who felt the gap.
We spent years preparing for system design interviews at top companies. We read all the books, watched all the videos, could name every component. And we still bombed the first few rounds.
The gap wasn't knowledge — it was practice under pressure. The ability to think through a real problem live, handle follow-up questions, and articulate trade-offs while drawing on a whiteboard.
ArchWyse was built to close that gap. Not with more content — but with deliberate practice in a setting that mimics the real thing as closely as possible.
"AI will write most of the code within five years. The engineers who thrive will be those who design the systems AI runs inside."
