When an employer says you cannot prepare, what should you do with the time?

Several employers state plainly that their first assessment needs no preparation, or that you cannot prepare for it. Believing them frees time. This guide lists who says it, in their words, and where the saved hours are better used.

Who says no preparation is needed

Each row comes from that employer's own page on this site. 7 employers, checked October 2026. Stated means the employer says it. Candidates report means we found it only in candidate accounts.

EmployerWhat it says
Grant Thornton UKAdvises against preparing in the usual way and suggests trusting your instincts. The Neurosight assessment typically takes under five minutes.
BDO UKSays no prior preparation is required, while linking a demo site with a practice question on its hints page.
Forvis Mazars UKSays none is needed: find a quiet space, read the instructions and answer honestly and instinctively. About five minutes, untimed.
Teach FirstSays it is not possible to prepare for the situational judgement test and that you should answer honestly from the information given.
AmazonSays most roles other than software engineering need no advance preparation for the work style and simulation assessments.
LinklatersIts Hong Kong page says no preparation is required for the Capp Online assessment, while also pointing to a preparation hub.
Standard CharteredSays there are no right or wrong answers in the behavioural section, so there is nothing to study for it.

Believe them, then look at why

When an employer says an assessment cannot be prepared for, the reason is usually that it measures style or judgement, not knowledge. Grant Thornton and Forvis Mazars describe short, adaptive assessments of potential. Teach First describes a situational judgement test where honesty is the instruction.

The sensible response is not to hunt for a trick. It is to protect the conditions: a quiet room, a working device, a clear head and no rush before you start.

The two-handed advice: a demo is not preparation

BDO and Linklaters show the nuance. Both say preparation is not required, and both point to a demo or hub. Reading these together, nothing needs studying, but seeing the interface once removes surprise. Spend ten or fifteen minutes on it and stop.

Amazon's position is similar: most roles need no advance preparation, but knowing its Leadership Principles helps you answer consistently, and the work sample simulations are strict about deadlines.

Where the saved time goes

The stages that follow are where you can improve. Grant Thornton adds a 20-minute written case study. Forvis Mazars and BDO follow with live or recorded video interviews. Teach First follows with a task-based assessment and a full-day centre. Standard Chartered's next stages are interview-led.

Our video interview guide and case study and written tasks guide cover the stages that benefit from practice. Write four short stories and say them aloud.

Be wary of anyone selling a preparation course for these

If an employer says an assessment cannot be prepared for, a site selling a course that claims to unlock it is promising something it cannot know. We cannot see live items either, and no site can. The honest tools are the employer's own demo, rest and a calm start.

Where a test does have a practisable part, such as numerical tables or passages, drill that part. The numerical reasoning guide lists which employers name one.

Frequently asked questions

Which employers say their first test needs no preparation?

On the pages we read, Grant Thornton, BDO, Forvis Mazars, Teach First and Amazon say so in their own words.

Should I still look at a demo?

If the employer links one, as BDO does, a short look at the interface is sensible. Then stop.

Can I do anything that helps?

Yes: protect the conditions. A quiet room, a working device, a clear head and enough time before and after.

Does no preparation mean no pass mark?

Not necessarily. These employers rarely publish how a result is used.

What should I practise instead?

The stages that follow: the written case study, the video interview and the assessment centre.
