The HDS does not measure who you are on a good day. It measures the eleven behaviours that show up when the pressure is on and the guard drops.
Free to start. Every item is generated fresh, marked with a full worked solution, and ranked on a 1–9 stanine band that recalibrates as more candidates practise.

What it measures
The HDS covers eleven derailers grouped into three clusters — moving away from people (volatile, sceptical, cautious, reserved, leisurely), moving against people (bold, mischievous, colourful, imaginative) and moving toward people (diligent, dutiful). Each is a strength overused: the same conscientiousness that makes you reliable becomes the diligence score that reads as micromanagement.
The format
Where marks are lost
Trying to score zero on everything. A flat, risk-free HDS profile reads as either a non-answer or a lack of self-awareness, and the reverse-keyed items make a uniformly denying pattern visible. The productive preparation is knowing which two or three scales are genuinely yours and being able to talk about how you manage them.
Why practise here
All 44 items across all 11 scales, in the four-point agreement format the real survey uses
Reverse-keyed items on every scale, so your consistency is actually tested
A profile showing which cluster your risks concentrate in, not just a list of numbers
Written in all eight app languages, so the wording is native rather than machine-translated
An AI debrief that turns each elevated scale into the question an interviewer would ask about it
Where you will meet it
Hiring stages where this format is commonly used. Persona Prep is not affiliated with Hogan and does not reproduce their questions — we build practice in the same format, from our own generators.
With Persona Prep Pro
One subscription covers the whole assessment library, not just this exercise — because almost nobody is invited to sit only one module.
The full aptitude library
SHL Verify, Aon cut-e, Hogan and Saville formats — numerical, verbal, inductive, deductive, mechanical, checking and the interactive modules.
A rank, not just a score
Every run is placed on a 1–9 stanine band that recalibrates as the candidate pool grows, so you know your position.
A course per exercise
What it measures, the trap that costs marks, and worked items from every format — then the exercise itself.
Unlimited fresh items
Everything is generated, so you never run out and never memorise a bank.
Written + voice AI coach
Reads your results across exercises and tells you which two to fix first.
Personality practice too
SHL OPQ32, Hogan HPI/HDS/MVPI, Saville Wave, ADEPT-15 and 16PF, with full profile reports.
The HDS measures eleven 'derailers' — behaviours that emerge under stress, when guard drops, or when someone is otherwise performing well. They are grouped into moving away from people, moving against people, and moving toward people. Each derailer is a strength taken too far.
Excitable (volatile), Sceptical, Cautious, Reserved and Leisurely make up the moving-away cluster. Bold, Mischievous, Colourful and Imaginative make up moving-against. Diligent and Dutiful make up moving-toward. Each is reported as a percentile with a risk zone.
It is not a pass or fail instrument, and a high score on a scale is a flag rather than a disqualification. What does read badly is a completely flat profile: it suggests either a non-answer or limited self-awareness, and the reverse-keyed items make uniformly denying response patterns visible.
Not by trying to score low on everything. Find out which two or three scales are genuinely elevated for you and prepare to talk about how you notice and manage them. That is the conversation an assessor actually wants, and it is the one an honest profile sets up.
Hogan
Motives, Values, Preferences Inventory
The MVPI is not about capability or risk. It asks what you actually want from work — and therefore which cultures you will thrive in and which will quietly wear you down.
Hogan
Hogan Business Reasoning Inventory
The HBRI reports two streams: reasoning with numbers and reasoning with arguments. Practise both, because a lopsided profile is what the report actually shows.
SHL
Verify Verbal Reasoning
A short business passage, a statement, and three buttons: True, False, Cannot say. The whole difficulty of this format lives in the third one.
