Meta Online Assessment — Format, Length and What It Tests
Run on
Karat, internal loop
What the assessment involves
- Karat-run technical screen with a live interviewer, roughly 60 minutes
- Two coding problems plus a short set of verification questions
Meta outsources a large share of its first technical screen to Karat, which means a real interviewer you have never met, working from a fixed script and rubric. The scoring is more mechanical than a Meta engineer's would be, and that cuts both ways — it rewards clear, structured explanation over rapport.
The part people underestimate
Karat interviewers follow the script closely. Talking through your approach before you type is scored; jumping straight into code and going quiet is not.
We have a longer walkthrough of this format in the Meta guide.
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.
Questions
What is the Meta online assessment?
Meta outsources a large share of its first technical screen to Karat, which means a real interviewer you have never met, working from a fixed script and rubric. The scoring is more mechanical than a Meta engineer's would be, and that cuts both ways — it rewards clear, structured explanation over rapport.
How long is the Meta assessment?
Length varies by role and team, but the stages listed on this page are the ones Meta 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 Meta assessment?
Karat interviewers follow the script closely. Talking through your approach before you type is scored; jumping straight into code and going quiet is not.
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.
