Interviews are stressful, but a full assessment event is one of the most challenging and intimidating things you will face in your career; it’s a full and rigorous test of your professional & mental ability. It’s not for the faint-hearted and if you are about to attend your first assessment event you will be genuinely surprised by how exhausted you feel afterwards.

Assessment events are referred to by various names, sometimes they’re called “assessment centres”, “assessment days” or “assessment events”. The language may differ but the principle is exactly the same: It’s an event to test a group of candidates’ suitability for a given role.

If you’re reading this then we assume you’ll be attending one soon (or hoping to attend one soon), so let’s look at what to expect in more detail.


So what is an assessment centre?

It’s not a location, it’s a process. It usually takes place at a company office, conference facility or a conveniently placed hotel.

It’s basically a big, in-depth interview process for several people.

The assessment centre process is used for all kinds of roles and for people at different stages of their career including:

  • graduate starter roles
  • corporate middle-management and executive roles
  • management selection
  • ongoing staff development & training

Assessment centres are usually used after the initial stages of the selection process due to the large amount of time and expense in conducting them. (They often follow an online assessment or initial job interview which is usually conducted by a third party, an agency or recruitment consultant.)

FACT: An average corporate employee in the UK will attend 3 assessment centres during their career.

So what happens at an assessment centre?

Assessors observe a group of candidates performing a variety of specially-designed tests (including psychometric tests) and exercises which provide specific information on the ability & mental capacity of each candidate.

Each of the exercises simulate aspects of the job description and work environment for the vacant role and allow the candidates to demonstrate how their skills match with those required to perform that role.

It’s an efficient way for big companies to quickly sort the wheat from the chaff and that’s why assessment centres have become so widely used.


68% of employers in the UK and 72% in the US now use some form of assessment centre as part of their recruitment/promotion process.

Performing under pressure is a great indicator of capability and assessment centres have become acknowledged as one of the most effective ways of quickly sifting through a large number of candidates and identifying talented people who will:

  • Perform their role with excellence
  • Get on well with other members of the team and fit in with the employer’s culture

How long do assessment centres last?

It varies from half-a-day to two full days. The more senior the role, the longer the assessment.

Who are the assessors?

Usually they will be a mix of HR consultants (in-house & external) and line managers and people at least one level above the position you have applied for.

Typically they will be ambitious and successful people who understand the qualities they expect to see in an individual performing the role you have applied for.

What will happen on the day?

Candidates attending an assessment centre will usually be welcomed with tea and coffee and there’ll be an arrival period of 30 minutes or so when candidates and assessors will mill around outside and chat ahead of the day’s events getting underway.

You’ll then be ushered into a communal ‘welcome briefing’ of some kind and you’ll receive an initial address together with the other candidates about the timing of the tests and exercises, location of rooms and housekeeping rules (fire alarms, washrooms etc).

And without further ado the assessment exercises will begin.

What exercises will I have to do?

The most common exercises are:

In addition to these practical exercises, there will almost always be some form of psychometric testing. Usually in the following areas:

Some industries also run other ‘reasoning’ tests such as Inductive, Mechanical or Spatial reasoning, which are essential for engineering & technical roles.

(Note: It’s increasingly common for psychometric tests to be completed online before the assessment centre itself and in some cases there will be a second suite of psychometric tests at the assessment event too!)


What happens during each exercise?

We’ll cover this with you in much more detail in each individual section, but briefly, during each test a group of observers will rate you on a range of predetermined criteria.

At the end of each exercise the observers compare each candidate’s performance to reach a consensus on overall performance.

Prior to each test, you will be given instructions describing the exercise you’re about to perform. You will not be told specifically what criteria will be measured during the exercise and (annoyingly) you will rarely receive feedback on your results or performance. (Though in some cases this may be made available after the event, usually within a few days.)
