A bounded fictional senior-backend work sample: interpret an API contract, diagnose retry and tenant-isolation defects, design tests, review a proposed patch, challenge release trade-offs and revise an evidence-based recommendation. Submitted artifacts are reviewed; code is not executed and no certification or automated hiring cutoff is implied.
Learn fictional online retailer Hearth & Home's delivery, returns and escalation rules, practise customer conversations, and prepare a supervised first-week handover. Two developmental checkpoints review actual practice evidence, not employment suitability.
Practice a fictional B2B SaaS negotiation from economic preparation through buyer discovery, compliant package revision, an honest follow-up and evidence-based reflection. Commercial correctness is checked separately from listening; closing at any cost is not the goal.
