Microsoft Online Assessment — Format, Length and What It Tests
Run on
internal loop, CodeSignal for some roles
What the assessment involves
- CodeSignal General Coding Assessment for some pipelines, 70 minutes, four tasks
- Otherwise a recruiter screen into a technical phone screen
Where Microsoft uses CodeSignal, it is usually the standard General Coding Assessment rather than a bespoke test — four tasks of increasing difficulty in 70 minutes, scored 1-850. The score is portable across companies that use the same assessment, which is unusual and worth knowing.
The part people underestimate
The GCA's later tasks are deliberately larger than they look. Budget time across all four before starting rather than perfecting task one.
How to prepare for it
Read the invitation email before anything else. It states the duration, the number of sections, and whether the session is monitored — and those are employer settings, so advice written about another company's version of the same platform will be wrong about them.
Then practise the specific shape above rather than general problem solving. An assessment with a debugging section rewards reading code; a recorded video stage rewards rehearsed, structured answers; a live pairing session rewards thinking out loud. Preparing for the wrong one of those is the most common way strong candidates underperform.

What is the Microsoft online assessment?

How long is the Microsoft assessment?
Length varies by role and team, but the stages listed on this page are the ones Microsoft uses. The invitation email states the exact duration for your sitting, and it is the only authoritative source — assessment configuration is set per employer and per requisition.
What trips people up in the Microsoft assessment?
The GCA's later tasks are deliberately larger than they look. Budget time across all four before starting rather than perfecting task one.
Can I retake it?
Retake policy is set by the employer, not the platform, and is usually stated in the invitation. Many companies enforce a cooling-off period of six to twelve months before you can sit the same assessment again, so treat the first attempt as the real one.
