FAQ desk
How do overlapping time zones work?
We publish a heatmap of live blocks versus async work before you pay. If you are in Vietnam and need zero Americas overlap, pick Async + office hours tracks—mentor replies are batched but documented.
Do you certify employment outcomes?
We issue a certificate of completion with module names and dates. We do not make hiring guarantees; we focus on artifacts you can show in interviews.
What software must I buy?
Lab images ship with open-source defaults. If a module uses a paid warehouse or BI tool, we list trial limits and who pays before week one.
Can teams attend together?
Yes—Field analyst tier includes paired enrollment. Larger teams should split across cohorts to keep review queues humane.
How are refunds initiated?
Email the enrollment desk with your agreement ID; processing steps and timelines are enumerated in the tuition adjustments page.
Case ledgers
Anonymized sketches showing challenge, intervention, and modest outcomes—no miracle metrics.
Aligning warehouse keys after a merger
Regional retail
Challenge: Two ERPs, duplicate customer rows, and nervous finance reviewers.
Intervention: Cohort pairs rebuilt grain statements, wrote SCD memos, and shipped paired dbt tests with annotated rollback.
Outcome: Reporting disagreements dropped in weekly ops review; team kept the memo template for new vendors.
Metric dictionary rescue for a product squad
B2B SaaS
Challenge: Three dashboards showing different activation counts with no owner.
Intervention: Facilitated SQL-first definitions, froze a two-week change window, and added row-level tests per metric.
Outcome: Product adopted a dated stub dictionary; analytics credits the visible unknowns section for faster sign-off.
Teaching ops to read anomaly monitors
Logistics
Challenge: Alerts fired too often; on-call ignored charts they did not trust.
Intervention: Layered thresholds with seasonality notes, human triage loop doc, and mentor shadowing on two incidents.
Outcome: Mean time to acknowledge improved modestly; ops started linking SQL snippets in tickets.
Hybrid lab for a finance-heavy cohort
Consumer credit
Challenge: Participants across three time zones with uneven SQL comfort.
Intervention: Async cells with pause points, rotating signal keeper role, and smaller scoped datasets.
Outcome: Completion held steady; peer review comments became more specific by week four.
