yours to edit ↗Software engineers (backend, infra, platform, full-stack) going after AI engineer and AI infrastructure roles, from mid to staff. Each interview is broken down for every level.
No. AI infra rounds are distributed systems with a model in the middle, so most of what you know carries over: load balancing, queues, caching, rate limits, streaming, idempotency. What's new is a short list: tokens and context windows, the KV cache and GPU memory, batching, retrieval and evals. The interviews teach those as they come up, on top of what you already know.
Our interviewer and candidate. Every interview is written by us from candidate reports, reviewed, and produced with AI voices, which is how we ship new problems and every level of each.

Pro is $79/year and lifetime $199 for a limited time; the bar at the top shows exactly how long you have. When it ends, it's $119/year and $299 lifetime for you, and it doesn't come back. Get Pro before then and you keep your price for as long as you stay subscribed. Monthly is always $39.
If your employer reimburses professional development, use "expense it" under the plans: it opens a short note to your manager with the price and the refund terms.
