AI Certification

Certify tool use, , knowledge and perspective at three levels. A SONUB video screen-sharing interview, not a written exam, sets your level — pick the one that fits you.

Screen-sharing interview

Share your entire screen through SONUB video, then carry out the tasks.

Example interview question: an AI that guesses the next word

Examiner Build an that guesses the next word while a student types study notes. Explain, step by step, how you would make it and how you would check that it works.

Answer in these four steps. Each step shows what to say, with a short example.

  1. 1. Goal

    Say what the AI does and for whom — what goes in and what comes out. Example: “When a student types ‘machine’, it suggests ‘learning’.”

  2. 2. Data

    Say what it learns from, how much, and what you keep aside for testing. Example: “2,000 sentences from my own notes — 80% to learn from, 20% kept for testing.”

  3. 3. How it works

    Say how it works inside and what you build it with. Example: “A counts which word comes after which and suggests the most frequent next word.”

  4. 4. Check

    Say how you know it works: one number you measure and one limit. Example: “On the test sentences, I count how often the real next word is among the top three suggestions. It looks only one word back, so long sentences go wrong.”

The examiner may change the topic — for example, a filter for spam messages or a lunch-menu recommender — but you answer in the same four steps. Higher levels explain each step in more detail, and the interview also has other questions and tasks for each level.

Design explanation practice examples

These invented examples illustrate ways to explain an AI design. They are not official answers and do not replace the interview requirements for each level.

A staircase of three wide steps; on each step the same small box sits on a sheet of paper, and the paper grows from a simple doodle on the lowest step to a numbered plan and then a detailed blueprint on the top step, with a child, a teenager and an adult beside the steps.
The question stays the same; the design under it grows more detailed at each level.
  1. Level 3

    I want an that guesses the next word in my diary. First I collect many of my own sentences. Then the counts which word usually comes after which. When I type a word, it suggests the word that most often came next. It is a machine I build, so I check whether its guesses are right.

  2. Level 1

    Goal: a next-word for my study notes, under the constraint “ only, no ready-made AI ”. : 2,000 sentences from my notes, 80% for and 20% kept for testing. Model: count word pairs in a table and turn the counts into . Evaluation: on the test sentences, how often is the real next word among the top three suggestions? Limit: it sees only one word back, so long sentences go wrong — the next would look at two words.

Use these examples to practise explaining a design. The real interview follows the requirements and time limits on each level’s page.

Constraints may be added

The question may restrict how you build. Higher levels carry heavier constraints.

  • A specific
  • A specific
  • Specialised in mathematical computation
  • Specialised in composing music

Required skill

Required at every level, from Level 3 to Level 1.

Shell Commands

The basic commands for handling and managing AI that has already been built, and the computer it runs on.

This certificate checks commands at every level, from 3 to 1 — how well you know them and how readily you use them. It does not test writing or programs: the examiner asks you to type commands right away, such as moving between folders, viewing, copying and deleting files, and installing, setting up and updating tools, and to explain what each command does. Shell commands do not build AI. They are commands for handling and managing AI that already exists — installing, running, setting up and updating AI tools ( such as and , and programs that run models) and working with the files they produce. The AI itself is built from and program . (Just using AI in a or app needs no . This certificate asks for shell commands because it tests how well you handle and manage AI tools yourself.)

The official exam is a single interview

There is no written exam and no practical exam. Every level from 3 to 1 is assessed only by a SONUB video screen-sharing interview, and the level is decided by how you explain and respond in that interview.

The examiner asks, you explain

When the examiner asks about a concept, a tool or a design, you explain in your own words what it is, why it is used and how to use it — not just a single memorised word. Follow-up questions check that you really understand.

Your level comes from the interview alone

There is no separate written score or practical score. The level is decided by how accurately and quickly you handle the questions and requests, whose depth differs at each level.

Practice online, any time

Practise the basics as often as you like on your own with the knowledge exam (multiple choice). Practice results are for your preparation only and are not part of the official record.
