How Do I Prepare for a HireVue Game Assessment in 24 Hours?
Assessment tomorrow? A realistic hour-by-hour plan for the final 24 hours: what to practise free, when to sleep, and the last-minute mistakes to avoid.
Deadline tomorrow, games never seen, mild panic — this is the single most common situation candidates land in, and the good news is that 24 hours is genuinely enough to move your score. Not because you will get smarter overnight, but because most of the applicant pool walks in cold, and familiarity is worth more than any other variable you can change today. Here is the plan, hour by hour.
The 24-hour plan at a glance
| When | What | How long |
|---|---|---|
| Now (evening before) | Familiarisation pass — play every game once or twice | 60–90 min |
| ~2 hours later | Targeted session on your two weakest games | 30–45 min |
| Tonight | Full night's sleep — the highest-scoring item here | 7–9 hrs |
| Assessment day | Pick your sharpest window; set the stage | — |
| 10 min before | Warm up on your easiest games | ~10 min |
The rest of this guide walks each block in detail. If you have longer than a day, skip to the "more than 24 hours" section — the same logic, paced out, beats any cram.
Today, as soon as you can: one familiarisation session (60–90 minutes)
Play every game type once or twice — all of them, not just the fun ones. They are all free here, they run exactly like the assessment versions, and the goal of this pass is not a score: it is that no mechanic surprises you tomorrow. Rule-decoding during the real test is the most expensive way to spend your first thirty seconds.
As you go, note your percentile after each game. You are looking for your two weakest categories — that is where tomorrow's points are cheapest.
If you only have time to cover the most common types, prioritise one from each family: a memory game (digit span), a numerical game (Numerosity), an attention game (flanker or Stroop), and a spatial game (mental rotation).
Early evening: one targeted session (30–45 minutes)
Go back to your two weakest games only. Read their strategy guides first — two minutes of technique beats twenty minutes of blind repetition:
- Memory games → chunking, and what a good span is
- Numerosity / arithmetic → endings-first scanning and left-to-right mental math
- Stroop / flanker → beating interference and ignoring the outer arrows
One technique per game, applied deliberately, beats a scattershot try-everything session. A few that pay off fast:
- Memory — chunk digits into pairs or triplets ("phone-number style"), so
4 9 2 7 1 5becomes492 · 715. Practise on digit span and backward digit span; calibrate with what a good digit span score is. - Numerical — scan the last digit of the target first to kill most candidate pairs before you compute, and do multi-step sums left-to-right. Drill on Numerosity and mental math.
- Attention/interference — answer the ink colour in Stroop and the centre arrow in the flanker test, treating the distractor as noise. See beating interference.
- Spatial — in mental rotation and Corsi blocks, remember the path or silhouette, not individual squares.
Then play three or four rounds applying the one technique. Stop while you are improving — the point of today is encoding, not exhaustion. Remember the games are adaptive: they get harder until you miss, so a rough final round tonight is the design finding your ceiling, not a bad omen. See how scoring and percentiles work if a low practice score is rattling you.
Tonight: sleep is the highest-scoring item on this list
Working memory and reaction speed are both sleep-sensitive — one short night measurably drags down exactly the abilities these games score. A full night of sleep will do more for tomorrow's percentile than three more hours of practice tonight. The all-nighter "cramming" instinct is precisely backwards for a cognitive test: there are no facts to cram, only a brain to rest.
Tomorrow: pick your window and set the stage
- Take it when you are sharp. Invites give you a window — use it. For most people that means late morning, after breakfast, not 1 a.m. before the deadline alongside the rest of the panicked pool.
- Caffeine, timed. Your usual dose, ~30–45 minutes before you start, so it peaks during the games. No heroic double espresso if you do not normally drink it.
- Fix the environment (5 minutes). Milliseconds are points in half these games, so run this checklist before you press start:
- Quiet room, door shut, nobody about to interrupt.
- Laptop on power, not battery — power-save mode can throttle the machine and add input lag.
- Stable connection — wired or strong Wi-Fi. A dropped connection mid-game is one of the few things that genuinely warrants a retake request, and it is avoidable.
- Notifications off — phone silent and face-down, desktop alerts muted, other tabs and apps closed.
- A real mouse for grid and spatial games (Corsi blocks, mental rotation, pathfinder); trackpads cost precision and time.
- Screen at eye level, decent light, comfortable seat — physical fidgeting is lost milliseconds.
10 minutes before: warm up
Play two or three quick rounds of the games you found easiest — not the hard ones, you are warming up your hands and attention, not testing yourself. A cold start reliably eats the first rounds of the real assessment; a warm-up hands you those points back. Then start.
What NOT to do in the last 24 hours
- Do not make the real assessment your first look at the games. You usually get one attempt, and retakes are employer-controlled.
- Do not sacrifice sleep for practice. Wrong trade, every time.
- Do not spiral over one bad practice score. The games are adaptive — everyone ends at their limit, feeling stretched is the design, not a verdict.
- Do not learn new "systems" the night before. One technique per weak game, practised until it feels natural. Tomorrow is execution day.
If you have more than 24 hours
Lucky you — the same plan stretched over a week beats any cram. Short daily sessions, weakest games first, one technique at a time. The complete guide to game-based assessments maps the whole battery, and the 10 proven tips cover the in-game technique in depth. Start with a free baseline run — it tells you in five minutes where your points are hiding.
If you would rather read how it went for somebody else before you start, how I passed my HireVue game assessment is one candidate's run through the same twenty-four hours, mistakes included.
FAQ
Is 24 hours really enough to prepare?
Yes — not because you'll get smarter overnight, but because most applicants walk in cold, and closing that familiarity gap is the biggest lever you have on the day. A single thorough familiarisation pass plus a focused session on your two weakest games removes the surprises that cost strong candidates their best rounds.
Should I pull an all-nighter to practise more?
No — that's the worst trade on this list. Working memory and reaction speed are both sleep-sensitive, so a short night measurably drags down exactly the abilities these games score. A full night's sleep will do more for your percentile than three more hours of practice. There are no facts to cram, only a brain to rest.
How much should I practise the night before?
Roughly 60–90 minutes to familiarise yourself with every game, then 30–45 minutes on your two weakest categories with one technique each. Stop while you're still improving. Beyond that you hit diminishing returns and start eating into sleep, which costs more than it gains.
Which games should I focus on with limited time?
Cover one from each family first — a memory game like digit span, a numerical game like Numerosity, an attention game like flanker or Stroop, and a spatial game like mental rotation — then spend remaining time on whichever you scored worst, since your result is a profile across the whole battery.
Should I warm up right before the real assessment?
Yes. Play two or three quick rounds of the games you find easiest about ten minutes before you start — enough to get your hands and attention online without spooking yourself. A cold start reliably eats the first rounds of the real test; a warm-up hands those points back.
