Multi-source aggregation
Company and recency records are compiled from maintained community datasets, then enriched with official LeetCode problem identifiers and public metadata.
Transparent and open source
About LeetMap Pro
LeetMap Pro is a free interview-preparation index that organizes company-wise DSA and SQL questions by frequency and recency. The project publishes its source code, data pipeline, update status, and correction channel so readers and automated agents can evaluate where the information comes from.
Dataset last published · 3,422 unique problems · 194 SQL problems
Normalization and deduplication
The build pipeline reconciles company aliases, normalizes problem slugs and IDs, merges overlapping reports, and removes duplicate records before publication.
Repeatable updates
An automated synchronization workflow regenerates the public JSON indexes and records source commit identifiers and publication time in the status feed.
Editorial organization
Pattern guides, SQL hubs, and the strategy roadmap add explanatory context while preserving direct links to the original practice environment.
Sources and ranking methodology
The primary community sources are the public liquidslr and snehasishroy company-wise repositories. Public LeetCode endpoints provide canonical problem metadata and the daily challenge when available.
Frequency percentages are comparative preparation signals derived from the available reports; they are not hiring probabilities or official statements from employers. Recency windows prioritize recently reported questions, while all-time views preserve the broader historical catalog.
Very small company pages are kept accessible for users but excluded from the XML sitemap and marked not to be indexed until they contain enough useful material. This focuses search crawling on stronger, differentiated resources.
Corrections, limitations, and independence
Interview reports can be incomplete, delayed, or inconsistent across sources. LeetMap Pro does not claim that every listed question will appear in a future interview. Use the frequency and recency fields to prioritize practice, not as guarantees.
Data corrections and reproducible issues can be submitted through the public GitHub issue tracker. The repository history provides an auditable record of data and code changes.
