How to Ace the HireVue Digitspan Memory Test

Digitspan presents a sequence of characters — numbers and letters — that flash on screen one at a time. Once the last character disappears, you must type back the entire sequence in the exact order it appeared.

The game is adaptive: get it right and the sequence grows by one character; get it wrong and it shrinks. The difficulty level you reach before making consistent errors is your effective score.

Most candidates start at length 4 and can reach 7–9 with practice. Elite performers hit 9–11.

Digitspan is a classic measure of verbal working memory capacity — your brain's ability to hold and manipulate information in the short term. It's one of the most replicated predictors of:

• Fluid intelligence (IQ)
• Learning speed in new roles
• Ability to follow complex instructions
• Performance under pressure

Employers use it because candidates with higher working memory consistently outperform peers across almost every professional role, particularly in finance, consulting, technology, and management.

The single most effective technique for Digitspan is chunking — grouping characters into meaningful 2–3 item clusters rather than trying to remember them individually.

For example, the sequence 7 K 4 R 2 B is very hard to hold as six separate items. But chunked as 7K · 4R · 2B, it becomes three pairs — much easier to recall.

With practice, you'll chunk automatically. The goal is to reach a point where a 7-character sequence feels like 3 items rather than 7.

As each character appears, mentally "say" it quietly in your head. Then, during the brief gap after the last character, rapidly repeat the whole sequence in your mind before typing.

This technique — called phonological rehearsal — leverages your brain's phonological loop, a short-term buffer specifically designed for holding verbal sequences. Using it consciously and consistently can extend your effective span by 1–2 characters.

Research on working memory training shows that consistent daily practice produces real, lasting improvements. Follow this schedule:

• Days 1–3: 3 rounds per day, focusing on sequences of length 4–5. Build the habit of chunking.
• Days 4–6: 5 rounds per day, targeting length 6–7. Push beyond your comfort zone each session.
• Days 7–9: 7 rounds per day, targeting 7–9. Focus on speed as well as accuracy.
• Day 10: 3 relaxed warm-up rounds only — don't exhaust yourself before the real test.

• Starting to type too fast — take a half-second to mentally replay the sequence before your fingers move
• Watching your typing instead of the screen — if you can touch-type, don't look at the keyboard
• Giving up after an error — the adaptive system will drop the length and you'll recover; stay focused
• Practising when tired — working memory is extremely sensitive to fatigue; always practise at peak alertness
