Microsoft OA Format and Platform

The Microsoft online assessment is delivered through a proctored online platform, most commonly HackerRank. Candidates receive the OA link by email after passing an initial resume review. The coding section typically contains 2 to 3 algorithmic problems with a 70 to 110 minute time limit.

Some Microsoft teams include an additional work simulation section that tests judgment and decision-making rather than coding ability. This section is not present for all roles. Check the LeakCode question database filtered by role type to see what past candidates for your specific role reported.

FAQ

Does Microsoft have an online assessment?

Yes. Microsoft uses an OA as the first technical screen for most engineering and technical roles. It is typically sent after a resume review and before any human interviews. The format has remained consistent across recent hiring cycles.

How hard is the Microsoft OA?

Based on candidate reports, Microsoft OA problems range from LeetCode medium to hard. Expect at least one problem that requires an efficient algorithm (not brute force) to pass all test cases within the time limit.

Where do these OA questions come from?

All questions in the LeakCode database are sourced from actual candidate reports on 1Point3Acres, Blind, Glassdoor, Reddit, and LeetCode. They are not AI-generated. Each question links to its source where the original report is public.
