LinkedIn OA Questions 2021: What Candidates Actually Saw

Last updated: May 2026

27+ LinkedIn online assessment questions reported by candidates who took the OA in 2021. Sourced from 1Point3Acres, LeetCode, Blind, Glassdoor, and Reddit. Data grows as new reports are added.

LinkedIn OA Format in 2021

The LinkedIn online assessment has followed a consistent format across multiple hiring cycles. Based on 2021 reports in the database, candidates typically see 2 to 3 algorithmic coding problems delivered through a proctored online platform (most commonly HackerRank). Some roles include additional behavioral or work-simulation components after the coding section.

Time limits reported by candidates range from 70 to 110 minutes for the full assessment. The coding problems are auto-graded, so edge case handling and runtime efficiency both matter. Partial credit is available on some platforms if your solution passes a subset of test cases.

How to Prepare for the LinkedIn OA

The LinkedIn OA is a timed, auto-graded coding test. Preparation is different from interview prep: you need to optimize for both correctness and speed, since partial credit requires passing test cases, not just showing reasoning.

  • Practice timed sessions. Set a timer for 35 to 45 minutes per problem and simulate the real constraint.
  • Focus on the topic clusters that appear most in LinkedIn OA reports: dynamic programming, graphs, arrays, and strings make up the majority of reported problems.
  • Read the problem constraints carefully before writing code. The constraints often reveal the expected time complexity and algorithm type.
  • Use the LeakCode database to review 2021 OA questions from actual candidates. Pattern recognition across multiple sightings is a stronger prep signal than any single mock problem.
  • If the OA includes a work simulation section, practice under realistic conditions. This section tests judgment and values alignment, not coding ability.
