FAQ

What’s the decisive factor between batch and streaming in a senior‑PM interview? The decisive factor is the candidate’s ability to tie latency promises to a concrete cost model and scalability plan. Panels at Amazon, Google, and Meta reject designs that ignore any of those three axes.

How many interview days should I expect for an LLM system design role at Google? Typical cycles in Q2 2024 involved five interview days, with a two‑week gap between the final loop and the offer. Compensation packages averaged $190 000 base, 0.04 % equity, and a $30 000 sign‑on.

Can I succeed with a pure batch design if the role is backend‑focused? Only if the product’s SLA tolerates > 200 ms latency and the budget caps are met. Most LLM‑driven user‑facing products at Stripe and Meta require sub‑120 ms, making pure batch a non‑starter.amazon.com/dp/B0GWWJQ2S3).
