Prompt Management Framework Review for LLM System Design Interviews

FAQ

What concrete metric should I mention when asked about prompt quality?
The judgment is to name Prompt Success Rate (PSR) first, because Amazon, Google, and Meta all treat PSR as the primary product health indicator; latency is a secondary concern.

How many interview days are typical for an LLM system design loop?
Most senior loops run 12‑15 days from screen to debrief; Google’s Q3 2023 loop lasted 12 days, Meta’s March 2024 interview spanned 14 days, and Amazon’s June 2023 interview consumed 14 days, indicating a consistent cadence.

What compensation can I realistically expect for an L5 PM in this space?
Expect base salaries between $175,000 and $200,000, with sign‑on bonuses from $25,000 to $40,000 and equity ranging from 0.03 % to 0.04 % at Google, Meta, Amazon, and Apple for senior LLM system‑design roles.amazon.com/dp/B0GWWJQ2S3).
