Sample Vetting Questions

Example questions at senior and principal level for Snowflake, with what a strong answer covers. They show the depth TeamStation AI tests. They are not a real candidate interview.

Query performance and cost

  1. Principal level, Mental Model. A query that ran in 20 seconds now takes 6 minutes on the same warehouse. How do you find out why?

    A strong answer covers: Query profile and where time goes; Partition pruning and data clustering; Spilling to local or remote storage; Data growth and skew.

  2. Staff level, Accuracy. When do you resize a warehouse, add clusters or change the query, and what does each cost?

    A strong answer covers: Concurrency versus single query size; Queued versus slow queries; Cost per second and idle time; Measuring the effect.

  3. Principal level, Cognitive Load. The monthly credit use doubled. How do you find the cause and put guardrails in place?

    A strong answer covers: Usage by warehouse, user and query; Repeated or runaway queries; Resource monitors and timeouts; Ownership and chargeback.

  4. Staff level, Procedural Knowledge. A dashboard refresh is slow every morning at 9. How do you diagnose and fix it?

    A strong answer covers: Concurrency and queueing; Result caching and materialization; Schedule changes; Warehouse separation.

Data modeling and pipelines

  1. Principal level, Mental Model. How do you design layers from raw data to business ready tables so that a mistake can be fixed without rebuilding everything?

    A strong answer covers: Immutable raw layer; Repeatable transformations; Lineage; Backfills and replay.

  2. Staff level, Accuracy. Two reports show different revenue. How do you find why?

    A strong answer covers: Definitions and filters; Late arriving and duplicate data; Time zones and currency; A single published definition.

  3. Principal level, Cognitive Load. Design incremental loading for a table of 5 billion rows that receives updates and deletes.

    A strong answer covers: Change capture; Merge cost; Idempotent loads; Reconciliation.

  4. Staff level, Procedural Knowledge. A pipeline loaded duplicate rows overnight. How do you fix the data and prevent it?

    A strong answer covers: Find the scope; Repair with a safe query; Unique keys and checks; Alerting.

Security and sharing

  1. Principal level, Accuracy. How do you protect personal data while analysts still do their work?

    A strong answer covers: Masking and row access rules; Roles by job; Audit of access; Testing as different users.

  2. Staff level, Mental Model. Explain how role hierarchy and grants decide access, and a mistake that exposes data.

    A strong answer covers: Grants to roles; Inheritance; Future grants; Reviewing effective access.

  3. Principal level, Cognitive Load. Design secure data sharing with 30 external partners.

    A strong answer covers: Sharing model; Per partner isolation; Cost allocation; Revoking access.

  4. Staff level, Procedural Knowledge. A table was shared too widely. How do you investigate?

    A strong answer covers: Access history; What was read and by whom; Closing the gap; Prevention.

Operations and reliability

  1. Principal level, Procedural Knowledge. A data load failed after 4 hours. How do you design so it can restart from where it stopped?

    A strong answer covers: Checkpoints and batches; Idempotent steps; Monitoring; Alerting that points to a cause.

  2. Staff level, Accuracy. What can time travel and cloning do for recovery, and what are their limits?

    A strong answer covers: Recover changed data; Retention windows and cost; Not a backup strategy by itself; Testing recovery.

  3. Principal level, Cognitive Load. Plan a migration from an older warehouse of 400 tables.

    A strong answer covers: Inventory and priority; Parallel run and comparison; Cutover; Retirement.

  4. Staff level, Clarity. Explain to a finance partner why costs vary by month.

    A strong answer covers: Plain words; Drivers; Controls; No jargon.

Data for analytics and AI

  1. Principal level, Mental Model. How do you make data trustworthy enough for a machine learning model and for executives?

    A strong answer covers: Quality checks at load; Definitions and ownership; Freshness measures; Lineage.

  2. Staff level, Accuracy. How do you test that a transformation is correct?

    A strong answer covers: Row counts and totals; Comparison with the source; Edge cases; Automated tests in the pipeline.

  3. Principal level, Cognitive Load. Design near real time analytics for 20,000 events a second.

    A strong answer covers: Ingestion path; Latency and cost trade off; Late and duplicate events; Monitoring.

  4. Staff level, Procedural Knowledge. A model scores the wrong customers after a schema change. How do you trace it?

    A strong answer covers: Lineage; Data versions; Contracts with upstream; Alerting.

Leadership and AI tools

  1. Principal level, Accuracy. An AI assistant wrote a transformation query. What do you check first?

    A strong answer covers: Join logic and duplicates; Full table scans and cost; Edge cases; Tests.

  2. Staff level, Clarity. Teams want their own warehouse each. How do you respond?

    A strong answer covers: The need behind it; Cost and control; Isolation options; A recorded decision.

  3. Principal level, Cognitive Load. Leadership proposes moving the warehouse to a different data platform. What do you do first?

    A strong answer covers: The problem being solved; Cost of moving; A bounded pilot; Decision record.

  4. Staff level, Procedural Knowledge. How do you mentor an analyst who writes correct queries that are too costly?

    A strong answer covers: Reading the query profile; Small rewrites with measured gains; Review habits; Visible progress.

The five Axiom Cortex axes, with one example each

  • Procedural Knowledge. Walk me through reading a query profile for a query that became slow. Looks for: Order of steps; What each step proves; What you do if the profile looks normal.
  • Mental Model. Why can a query scan far more data than it needs? Looks for: Pruning and how data is stored; Filters that cannot prune; The right fix.
  • Accuracy. What does time travel protect against, and what does it not? Looks for: Correct limits; Retention and cost; Says when it is unsure.
  • Clarity. Explain to an executive why two dashboards show different revenue. Looks for: One cause named; One decision for the listener; Plain words.
  • Cognitive Load. The morning load failed, dashboards are stale, credit use is spiking and two teams blame each other. What do you do first, second and third? Looks for: A clear order; Facts kept apart from guesses; Stays correct as facts change.
