Reported Vanta coding questions
Implement `uniq` — Unique Lines in a File
3/5This reported Vanta interview question challenges candidates to build a command-line tool that extracts and displays unique lines from a document. The exercise evaluates your ability to manage system resources, process text streams efficiently, and handle massive files that exceed available memory limits. You will need to demonstrate strong design skills regarding file I/O operations and data structures. Access the complete problem description and expert model solution with a subscription.
asked June 2026IOHashingStreamingEmployee Training Status + Group Tree Aggregation
3/5This Vanta interview problem requires you to evaluate employee compliance status regarding security training across specified windows and aggregate these metrics hierarchically across organizational group trees. You will build logic to compute exact overdue days for individuals and roll those statistics upward to calculate cumulative headcounts and total delays for overarching departments. The challenge tests your ability to handle date arithmetic alongside recursive tree traversal and data aggregation. Access the full problem details and a clean model solution by subscribing today.
asked March 2026TreeDFSHashmapTask Dependency Resolution (Topological Sort)
3/5Reported during interviews at Vanta, this challenge requires you to compute a correct execution sequence for a collection of interdependent jobs. It tests your proficiency with graph traversal algorithms, cycle detection, and topological sorting within a practical build-system context. You must filter and order tasks properly while eliminating redundancies to ensure a reliable deployment workflow. Access to the comprehensive problem breakdown and verified solution code requires an active subscription.
asked February 2026Topological SortGraphDFSTest Run Status Monitor (Failing → Passing Windows)
4/5Design an efficient logging and monitoring system frequently encountered in Vanta technical evaluations to track system reliability metrics and incident recovery times. This problem challenges your ability to ingest sequential state change events and build high-performance query handlers that calculate recovery durations and identify peak periods of widespread service degradation. Success depends on optimizing your data structures for fast lookups over streaming inputs. Gain full access to the architectural guidelines and reference implementation with a paid subscription.
asked July 2025HashmapInterval AggregationIntervalsFrontend Practical Coding — Work Against a Provided API
3/5In this practical frontend engineering assessment reported at Vanta, candidates must build a React component that interacts with a tricky, imperfect REST API using TypeScript. The task tests your ability to execute asynchronous network requests, parse and filter returned payloads, handle state effectively, and navigate minor quirks in a sandboxed development environment. To view the complete project specifications and the ideal implementation approach, a paid subscription is required.
asked July 2025FrontendReactTypescriptWord Pattern / Meta-Pattern Match (Backtracking)
3/5This Vanta interview challenge explores an advanced pattern-matching variant where numeric tokens must consistently align with words in a candidate string, with follow-ups introducing set-based allowed values solved via backtracking. It evaluates your skills in managing bi-directional mappings, constraint propagation, and recursive search algorithms.
