FAQ

What part of the LeetCode lakehouse question is actually useful?
Only the storage‑layer sketch is marginally relevant. Real Databricks loops assign 40 % weight to compute & metadata, which LeetCode omits entirely. Use the question as a warm‑up, not a template.

How long should I spend on each layer during the interview?
Allocate 2 minutes to ingestion, 3 minutes to storage, 4 minutes to metadata sharding, 2 minutes to compute (Photon), and 2 minutes to security. The total 13‑minute design fits the typical 45‑minute interview slot after follow‑up questions.

Can I mention LeetCode’s solution and still get a Hire?
Only if you immediately pivot to DLAF and critique the LeetCode approach. The panel will note “candidate is aware of the gap” and may give a +1 vote, but without the deeper layers the default is No‑Hire.amazon.com/dp/B0GWWJQ2S3).
