Design a tiered API rate limiter
Pick token bucket or sliding-window, key limits by partner tier, track counters in a shared store like Redis, decide at the edge.
Public API design versus internal API design
Public needs strict versioning, long deprecation, scoped auth like OAuth and API keys, and polished docs; internal can move faster.
Decommission a depended-on API gracefully
Map consumers and usage, provide a migration target, announce a versioned timeline, decommission only after traffic hits zero.
Unify behavior, billing, and CRM data
Ingest events, sync Stripe and Salesforce into a warehouse, resolve identities to one customer, model unified metrics.
Prepare for a launch traffic spike
Model expected load, load-test to find the first bottleneck, scale and cache, add graceful degradation and a queue for spiky writes.
Instrument an onboarding flow for analytics
Track each onboarding step plus the activation milestone, define a clean event schema with stable IDs, send reliably via batching or server-side.
Evaluate a high-risk full rewrite
Surface rewrite risk with POCs, propose incremental displacement like Strangler Fig, quantify the cost of stalled features.
Build the case to deprecate a legacy feature
Quantify cost versus value and who the 2% are, propose migration paths and a phased sunset, weigh velocity against trust.
Estimate and de-risk an ambiguous initiative
Decompose into phases that front-load learning, run spikes to retire risk, communicate estimates as ranges tied to milestones.
Add a Pro plan and gate features
Model plans and entitlements as data, enforce server-side via a central check, decouple the gate from feature code.
Architect today for a loosely defined future
Isolate volatility behind stable interfaces, use ports and adapters, keep changes reversible and deferred.
Product strategy versus go-to-market strategy
Product strategy defines the product and roadmap; GTM defines launch, pricing, channels, and audience; they overlap at positioning.
Quantify tech debt and pitch it to a PM
Quantify probability times impact, tie debt to velocity or incident cost, and propose scoped phased work.
Platform team metrics versus product team metrics
Measure adoption, reliability SLOs, integration time, and self-service ratio over user engagement.
Move from flat to usage-based billing
Reliable usage capture, idempotent aggregation into billing periods, and reconciliation with the provider.
Engineering input in a Jobs to be Done workshop
Frame the underlying job and measurable outcomes the user wants, decouple from any solution, then let features compete to serve them.
Technically analyzing a competitor's product
Probe their stack, performance, APIs, and architecture via public signals and ethical inspection, identify gaps and parity needs, feed differentiation and risk into the…
Technical principles for building a learning-focused MVP
Validate the riskiest assumption first, use off-the-shelf and manual where possible, instrument for learning, defer scalability and polish.
Design a measurement framework and experimentation plan for a risky feature rollout
This tests balancing upside against operational risk. A strong answer defines guardrail metrics for stability and cost, sequences canary before A/B tests, and sets rollback thresholds. A red flag is ignoring latency or cost to chase engagement lift.
Explain the difference between Objectives and Key Results in OKRs
Objectives inspire direction; Key Results are measurable proof; cite an engineering example on technical quality like uptime.
