Dataiku ML Practitioner exam-day guide
Dataiku ML Practitioner · Prepare for the day ahead.
Your checklist
Government-issued photo ID
Bring the exact ID name that matches your registration. If your registration name differs from your ID (for example, a preferred name or a married-name mismatch), contact the provider before test day to correct it; proctors commonly refuse entry on a name mismatch. Confirm the accepted ID types with the provider, since remote-proctored and test-center deliveries can differ.
Appointment confirmation and login details
Have your confirmation email, registration/order number, and the exam platform URL and credentials ready. For a remote-proctored sitting, test your login ahead of time so you are not resetting a password minutes before the start.
Quiet, private room and a stable connection (remote delivery)
Use a room with a closed door, no other people, and a clear desk. Wired or strong Wi-Fi, a working webcam and microphone, and a charged laptop are baseline. Confirm with the provider whether remote proctoring is offered for this exam and what the room and system requirements are.
System or browser check completed in advance
Run any provider-supplied compatibility or proctor-launch check at least 24 hours ahead. Install required browser extensions or secure-browser clients then, not on test morning, so a failed install does not consume exam time.
Knowledge of the allowed-aids policy
Confirm with the provider whether scratch paper, a pen, a calculator, or any reference material is permitted, and whether an on-screen notepad is provided. Do not assume; treat unlisted aids as prohibited.
Dataiku concepts refreshed, not new material
In the last days, review your own notes on visual recipes, the Prepare recipe processors, code recipes (Python/R/SQL), the Flow and datasets, scenarios and metrics, and model training/evaluation in the visual ML interface. Do not start a new course the night before.
Practice with the exam's question style
Rehearse scenario-based reasoning: given a business goal and a data shape, choose the right recipe, processor, or evaluation metric. If the provider publishes a sample or tutorial, use it to calibrate wording and difficulty.
Water and a light snack for before the test
Hydrate and eat lightly beforehand. Confirm with the provider whether any break is allowed and whether leaving the camera view during an unsupervised break is permitted; many proctored exams do not pause the clock.
Backup plan for technical failure
Know the provider's support contact and their procedure if the connection drops or the proctor session fails. Note your registration number so support can locate you quickly.
Time budget and question strategy decided
Write down your per-question time target (total minutes divided by question count, minus review time) and your rule for flagging and moving on. Decide in advance how many flagged items you will revisit.
Arrival or launch time confirmed
Check whether you must arrive or launch early for check-in. Confirm the exact start time in your own time zone, since providers sometimes display times in a different zone.
Confirm exam scope and format with the provider
Verify the current number of questions, time limit, passing score, and whether the exam is proctored or unproctored. These details change between versions, so treat any third-party figure as unverified until the provider confirms it.
Plan the day
Do a final scope pass using the provider's official exam guide and map each listed topic to your own notes. Identify your two weakest areas, such as window functions and SQL recipes, or model evaluation and overfitting, and spend the remaining study time there. Stop adding new resources.
Run the provider's system or browser check and install anything required. Confirm your appointment time in your local zone, verify the ID you will present matches your registration name, and read the allowed-aids and room rules once, carefully.
Do a timed practice set or work through end-to-end scenarios: build a small Flow mentally from ingestion to a scored model, naming the recipe type and key settings at each step. Review why wrong answers are wrong, not just the right answer.
Light review only: skim your one-page summary of recipe types, common Prepare processors, code-recipe entry points, and evaluation metrics. Prepare your workspace, lay out your ID, and charge devices. Get a normal night's sleep rather than cramming.
Eat, hydrate, and avoid heavy caffeine if you are jittery. Re-run a quick connection and camera check, close background apps and notifications, and silence your phone. Put away anything not explicitly allowed.
Log in or arrive at the test center early for identity verification and check-in. Keep your ID and confirmation number within reach. Do not start last-minute studying that could rattle your confidence.
Read each question fully and watch for qualifiers such as 'most appropriate', 'first step', or 'least likely'. Answer what you know, flag anything uncertain, and move on. Do not let one hard scenario consume several minutes.
For scenario questions, restate the goal and constraints to yourself, then eliminate options that are technically valid but wrong for the stated goal, or that misuse a tool (for example, choosing a code recipe where a visual recipe is asked for, or optimizing the wrong metric).
Watch the clock and reserve the last portion of your time for flagged items. Change an answer only when you can name the specific reason it is wrong; second-guessing without a reason usually hurts. Confirm you have no unanswered questions before submitting.
Rules to check
Present valid government-issued photo ID matching your registration name exactly. If you are unsure which ID types are accepted, confirm with the provider before test day.
Follow the provider's rules on allowed materials and environment. Unless the provider explicitly permits it, assume scratch paper, phones, smart watches, notes, and a second screen are prohibited, and keep your desk clear.
Do not communicate with anyone other than the proctor during the exam, and do not let anyone enter your testing space. For remote delivery, stay in the camera view and keep your face visible.
Confirm with the provider whether breaks are allowed, whether they pause the clock, and what you must do before and after a break. If no break policy is stated, plan to complete the exam in one sitting.
Attempt every question unless the exam penalizes wrong answers; confirm with the provider whether scoring penalizes guessing. Unanswered questions usually score as incorrect.
Understand the scoring before you sit: confirm the passing score, whether results are reported immediately or later, and how many attempts are permitted. Do not rely on forum-reported numbers.
Report any technical failure to the proctor or provider support immediately and follow their instructions. Do not attempt to troubleshoot in a way that takes you out of view or off the session without telling the proctor.
Keep exam content confidential. Do not record, screenshot, or share questions, and do not discuss specific exam items afterward in a way that reproduces them.
