• Review getEvents endpoint for readability, performance, scalability, securityHard

  A StubHub software-engineer technical-screen system-design exercise: review and fix a GET /events HTTP handler that loads related data (venue, performers, tickets, transactions) per event. Candidates must find and fix the N+1 query, then harden the endpoint across readability/architecture, performance (pagination, indexing, caching), scalability (timeouts, retries, rate limiting), and security (authN/authZ, injection, PII), with trade-offs, SLOs, and a test plan.
