Can you explain the answer—not just name the tool?

These questions come from the guides. Try answering aloud, then reveal an answer outline to compare your reasoning. The full PDFs develop the topics with explanations, code and projects.

Preparing for interviews at leading companies?

The Azure guide includes 16 company-focused sections, including Amazon, Deloitte, Accenture and PwC. Use them to practise company-style scenarios and structure your preparation.

Independent preparation material; company labels do not verify that a specific question was asked by that employer or imply endorsement.

Azure + DatabricksPerformance

How do you debug skewed joins in Spark?

Azure guide · page 7 · Q12

Reveal answer approach

Start with the Spark UI: compare task durations and partition sizes, then profile the hot keys. Consider a broadcast join when the smaller side fits, AQE skew handling, or salting with a correct join strategy. Explain the trade-offs before changing cluster size.

Azure + DatabricksData modelling

How do you design SCD Type-2 logic in Databricks using Delta MERGE?

Azure guide · page 8 · Q15

Reveal answer approach

Track effective dates and the current-row flag. Detect changed business keys, expire their current versions and insert new versions using a staged merge or coordinated operations. Explain how retries avoid duplicate versions and how late changes affect history.

Condensed teaching outline adapted from the guide.

Snowflake + dbt + AWSAdvanced

How do you handle late-arriving facts and late-arriving dimensions?

Snowflake guide · page 16 · Q16

Reveal answer approach

Detect late facts using ingestion progress, then merge an appropriate lookback window. Match historical facts to the dimension version valid at event time. For missing dimensions, retain the fact with an unknown or inferred member and reconcile it later.

Condensed teaching outline adapted from the guide.

Snowflake + dbt + AWSArchitect

How do you design a pipeline that is idempotent and replayable?

Snowflake guide · page 78 · Q23

Reveal answer approach

Retain immutable raw inputs, use deterministic writes on business keys, and order changes by source sequence rather than arrival time. Reuse parameterised processing for backfills, track progress, and reconcile results so retries and replays do not duplicate data.
