# DeepBrain AI interview preparation

Interview preparation package for PJ, prepared 23 October 2026. Website target: **deepbrain.define-labs.com**. Publication authorized by PJ on 23 October; verified status is recorded in qa/Release_Report.md. Interview date, interviewer and format remain unknown.

Start with `docs/01_Company_and_Role_Profile.md`, `docs/05_SBI_Answer_Bank.md`, then `Study_Guide.md`. The browser guide is built from the same authored Markdown sources. The organizing skill is selecting the important point, answering in one sentence, giving one SBI example and stopping.

Contents: company/role profile and translated benefits; evidence map; strategy and proposed 23-section PRD; 32 bespoke metric definitions (28 measured on synthetic records; four proposed instrumentation gaps); 24 SQL/CSV/chart exercises; reproducible SQLite, editable executed notebook and separate model answers; separate local Metabase database/collection with four dashboards; source ledger, reusable handoff and QA report.

Metabase is shared infrastructure with a separate DeepBrain project, not a second server. No SORI source, database, card formula or visualization was overwritten. See `qa/metabase_validation.json` and `metabase/links.json`. All operating/evaluation numbers are fictional practice values. Public claims and authorized page observations remain separate; all internal company baselines/targets are unknown.

Browser build: `/Users/pj/Documents/Sori/.venv-analysis/bin/python scripts/build_website.py`. Local preview: `python3 -m http.server 8773 --bind 127.0.0.1 --directory website/dist`. Exact URLs must be verified before sharing. Reading progress, notes, rubric scores and categorized highlights are browser-local with JSON export/import. No paid service or external model is required for the guide. The read-aloud player uses device voices.

Data generator refuses existing databases. For reproduction use a new empty folder; do not run it against saved work. See `lab/README.md`, `lab/requirements.txt` and `HANDOFF.md`. The website bundle excludes private CVs, credentials, Metabase app state and raw research HTML. The local source folder contains private CV text/contact information; do not publish the whole folder blindly.

If the local guide stops, double-click `Start DeepBrain Guide.command` in this folder. It binds only to loopback and does not alter SORI servers or data.

## Expanded Metabase

DeepBrain-only database 3 / collection 17: 27 reusable metrics, 13 source models, 27 metric-backed views, a 32-definition registry, 24 operational questions and 13 relationship views. Eight dashboards include the nine-tab library. See [parity report](qa/Metabase_Parity_Report.md). All source data remain fictional/proposed where labeled.
