Suggest creators to follow on a one-way graph of 40 billion edges: random walks and SALSA, follow communities, two-tower retrieval and a ranker for follows people keep; one-hour boards for junior, senior and staff, with theory.
Machine-learning engineers designing data, training and model systems.
Your approach: Explain the data, learning or model lifecycle in the brief. Support relevant quality and operating targets with evidence.
Design Creator Recommendations (Who to Follow). Suggest creators to follow on a one-way graph of 40 billion edges: random walks and SALSA, follow communities, two-tower retrieval and a ranker for follows people keep; one-hour boards for junior, senior and staff, with theory. Work from the scoping questions below. State assumptions for any unspecified load, guarantee or target, then trace your design end to end. Explain one difficult case and a credible alternative; the worked example is a reference, not a required implementation.
Resolve the scoping questions for Creator Recommendations (Who to Follow). Separate stated behavior from assumptions, and identify what is outside your design.
Declare relevant volume, latency, freshness, quality or cost targets with units. Show calculations or an evaluation plan that can test them; unspecified targets are your assumptions, not hidden pass criteria.
Explain how your guarantees hold in a difficult case relevant to this subject. Address: Who may be suggested? Cold start?
Identify users, required behavior and exclusions. Answer: Which surfaces? What is success?
Define the information owned by the system and the inputs, outputs and errors at its boundaries. Resolve: Scale? Latency?
Estimate the dominant workload and resource demand with units and explicit assumptions. For a learned system, also state how quality is measured and what data is available.
Draw or describe the responsibilities needed for Creator Recommendations (Who to Follow). Trace a representative request, event or job from its input to a visible result; identify durable state owners.
Walk through a difficult case step by step, including detection and recovery. Consider: Freshness? Labels? Who may be suggested? Cold start?
Compare a credible alternative using your chosen workload and guarantees. Explain a remaining risk, a signal to watch and when you would change the design.
