8090 interview field kit · ten hours of rehearsal
A company-specific system-design curriculum built from 8090’s platform, enterprise delivery work, public challenges, engineering writing, changelog, and hiring signals. Every mock is a complete interviewer–candidate conversation—not a prompt list.
Start with 01, then follow a track or attack your weakest domain. All numbers inside the interviews are explicitly labeled mock constraints.
Connect business intent to code and tests while durable, multi-model agents work under versioned context, quotas, and approval.
Core Software Factory product + Chamath audit/harness thesis.
Turn hostile fax/PDF packets into evidence-backed decisions with calibrated abstention, human review, and reproducible offline execution.
MIB challenge + DME document intelligence + regulated delivery.
Index huge, permissioned repositories incrementally and detect traceable requirements-to-code drift without blocking development.
GitHub/GitLab integration, multi-repo search, Drift Bot, CMS-scale code.
Let humans and agents coauthor structured requirements and blueprints without losing identity, approval authority, or history.
Realtime multiplayer, suggestions, version history, changelog race fixes.
Recover traceable business rules from millions of lines of COBOL/Assembly and make them reviewable across several claims systems.
ClaimsCore case + ESRD pricer repository.
Reconstruct a financial black box from traces, preserve quirks, shadow safely, then introduce intentional policy corrections.
Top Coder challenge + 8090 modernization positioning.
Validate part definitions in real time, autoapprove compliant work, route exceptions, and keep a legacy PLM authoritative.
BISSELL production customer story.
Build an explainable deterministic prefilter that reduces expensive vendor review without hiding false-positive or appeal risk.
8090 insurer/payment-integrity delivery case.
Ingest noisy feedback, preserve evidence, cluster it into explainable themes, and propose traceable Work Orders.
Software Factory Feedback module and automated triage.
Safely connect users, projects, agents, repositories, Slack, and external MCP tools across changing OAuth scopes.
Documented GitHub/GitLab/Slack/MCP integrations.
Execute untrusted submissions, score business risk deterministically, prevent leakage/gaming, and prove reproducibility.
MIB/Top Coder evaluators + medical evaluation framework.
Meter multiple model/tool providers accurately, reserve budgets before work, enforce quotas, and reconcile late cost data.
Software Factory model catalog, token costs, and usage dashboard.
Schedule hours-long agent DAGs with leases, checkpoints, scoped side effects, fair queues, cancellation, and recovery.
Durable Agents, subagents, automations, and scheduler failure signals.
Ingest many artifact formats and serve citation-rich retrieval without leaking stale, deleted, or unauthorized content.
Software Factory Knowledge Base and MCP search/read.
Draft evidence-grounded medical responses with sentence citations, expert stages, immutable snapshots, and quality release gates.
8090’s detailed medical-authoring engineering post.
Enrich and score hundreds of millions of claim rows reproducibly, then route explainable leads to investigators.
Public Medicaid claims analytics repository.
Unify six legacy data sources, surface explainable care opportunities, work offline during visits, and learn from clinician feedback.
8090 Medicare Advantage recommendation case.
Discover, rank, and migrate hundreds of dependent legacy applications through parallel agent/human assembly lines.
8090 Modernize path + EY portfolio/discovery emphasis.
Operate one product across shared SaaS, dedicated regions, customer VPCs, and air gaps without losing release or audit control.
8090 Enterprise host/maintain promise + sovereignty direction.
Record reproducible AI action receipts while honoring retention, legal hold, derived-data deletion, and cryptographic integrity.
Chamath AI-risk audit chain + Factory traceability/privacy requirements.
Use routes to build depth without doing twenty in numerical order.
Best five if time is short.
Control planes, collaboration, scheduling, knowledge.
Evidence, decisions, claims, authoring, clinical work.
Recover intent, establish parity, migrate by slices.
These are predictions, not leaked 8090 questions. Company/customer metrics in the research report are labeled; all scenario traffic and SLO values inside the mocks are invented constraints for design practice.
