IBM OA Questions 2024: What Candidates Actually Saw

Last updated: May 2026

15+ IBM online assessment questions reported by candidates who took the OA in 2024. Sourced from 1Point3Acres, LeetCode, Blind, Glassdoor, and Reddit. Data grows as new reports are added.

IBM OA Format in 2024

The IBM online assessment has followed a consistent format across multiple hiring cycles. Based on 2024 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 IBM OA

The IBM 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 IBM 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 2024 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.

FAQ

What does the IBM OA look like in 2024?

Based on 2024 candidate reports, the IBM OA typically includes 2 to 3 coding problems and runs 70 to 110 minutes. Topics lean toward dynamic programming, graphs, arrays, and strings. Some roles include a work simulation section after the coding component.

How long is the IBM OA?

Most candidates report 70 to 90 minutes for the coding component. Roles with additional work simulation sections extend the total time to 110 to 150 minutes. Check your invitation email for the exact time allocation for your specific role.

What platform does IBM use for the OA?

IBM uses HackerRank or its own proprietary platform depending on the role and hiring cycle. Your invitation will specify the platform. Both platforms support multiple languages including Python, Java, C++, and JavaScript.

Are these real IBM OA questions?

Yes. All questions in the LeakCode database come from candidate reports on 1Point3Acres, Blind, Glassdoor, Reddit, and LeetCode. They are not AI-generated. Each question links to its source where available.
