Your AI copilot, live in the interview

Invisible overlay. Three AI panels. One question, answered before you need to speak.

Interview AI Buddy — TECHNICAL MODE
LIVE
Interviewer
"Design a system that can handle 10 million concurrent users sending real-time notifications."
QUICK
1.3s

Use a pub/sub architecture with a message broker like Kafka. Fan-out via WebSocket servers behind a load balancer. Shard by user ID. Cache recent notifications in Redis with 24h TTL.

TECHNICAL
2.1s

At 10M concurrent, single-machine WebSocket won't scale. I'd partition users across WebSocket clusters using consistent hashing. Kafka handles event ingestion with 10–20 partitions for throughput. Redis Streams for fan-out, with a delivery guarantee layer using acknowledgment tokens. For mobile, fall back to APNs/FCM push.

GENERAL
2.4s

The key trade-off here is between push and pull models. Push scales better for real-time but adds infrastructure complexity. I'd mention exactly-once delivery challenges, and how at 10M scale you accept at-least-once semantics with idempotency on the client side. This shows systems thinking, not just component knowledge.
