This course contains the use of artificial intelligence.
"Your answer was correct. It sounded rehearsed."
That is a real coaching note, and it is the reason this course exists.
Everyone can find the standard pipeline. Retrieval, ranking, re-ranking, serving, metrics. Interviewers know that, which is why a fluent walk through the standard pipeline no longer passes a senior loop. What they are listening for is whether the judgment is yours, growing out of this problem, or imported from a different one.
So the course teaches both halves.
The eight-step spine gives you a structure that never leaves you stranded. The differentiator doctrine gives you the opening move that separates you from everyone reciting: before you touch the pipeline, name what makes this system different. Ads means freshness, calibration, and bid. Nearby places means distance filtering in retrieval. Harmful content means label scarcity and adversarial drift. Two sentences, and the room hears that you know which system you are designing.
The format is design-along, not lecture.
Each case gives you the prompt, stops and lets you attempt the stage, then shows the worked decision, then fires the follow-ups interviewers actually ask. Those follow-ups were mined from years of coaching sessions and rebuilt fresh for the course.
Five full cases:
personalized news feed, ads click prediction, harmful content detection in the LLM era, and a catalog module that maps any new prompt to its nearest solved family, so an unfamiliar question stops being a cliff.
The hard parts get the most room.
Data and labels is a full module, because it is where most candidates overspend and still say nothing scoreable. Serving and monitoring is a full module, because "how did you deploy your model?" is a documented screen-killer.
It ends with two timed mocks and a scoring rubric
you run against yourself, at the senior bar rather than a passing one.
Module 1 is free, along with the first ten minutes of the news feed case.
