An assessment centre is an extended period of interviews, tasks and assessment exercises, organised by recruiters for small groups of candidates.
Companies use assessment centres to find out how candidates perform in various situations – in particular group tasks, which are often reflective of real work-based scenarios.
This type of assessment is frequently used by large graduate employers who wish to recruit a cohort of candidates for a given year of entry.
The term ‘assessment centre’ is used because employers usually conduct these extended appraisals in a single location: either an office of the employer themselves or at a third-party venue, such as a hotel or function room.
You’ll also hear the term 'assessment day', which reflects that these extended periods of assessment last for the best part of a day. Many last for a full working day between usual office hours, and some even last longer (up to three days).
An assessment centre is usually coordinated by a group of assessors or recruiters that includes members of an employer's HR team, departmental managers and partners at the firm.
In theory, this makes the process more objective because the final decision on each candidate must be agreed on – using a range of structured assessment methods – rather than by an individual’s preference.
Assessment centres are routinely used by larger graduate recruiters to assess candidates. Smaller companies may not be able to organise entire assessment days due to the expense involved, but often introduce elements of them into their interview processes, such as psychometric tests and in-tray exercises.
The cost of putting a candidate through an assessment centre varies depending on the length, tasks involved and amount of employees required to assess candidates. Employers could be spending as much as £3,000 on each candidate who attends.
If you want to find out if the scheme or job you're applying to includes an assessment centre as part of its application process, you should be able to find out by checking the company’s website or the forum here on WikiJob.
Employers are prepared to invest in assessment centres because they believe them to be the most accurate means of recruiting the right people for their vacancies.
Research carried out by business psychologists demonstrates that traditional job interviews are not an accurate way to predict a candidate's future performance. Interviews may also be affected by an interviewer's pre-conceptions or bias.
The tasks they are asked to perform usually reflect the work they will be doing if hired, and consequently their ability to perform at assessment is thought to be a direct indication of their potential ability to do the job in question.
The group aspect also allows assessors to find out about candidate's key personality traits, such as how well-suited candidates are at working with other people, and their key strengths and weaknesses.
Consequently it is thought that assessment centres are the fairest and most accurate way to recruit staff.
If used, assessment centres are usually the penultimate stage of the interview process, prior to the final interview.
This is because they are expensive (they take up a considerable amount of time and resource to organise) and therefore it’s in an employer's interests to invite only those applicants most likely to be hired.
Assessment days are unique to the organisation running them. Employers will create the assessments based around their business, ensuring that they assess the skills that are most important to them.
The tasks and tests will typically be made up of a selection of the following:
The structure of the assessment day will vary depending on a number of factors; a typical day would be as follows.
Candidates will arrive early, usually around 9 a.m., and will be welcomed to the company with refreshments. There’s usually a period of around half an hour where candidates and recruiters can interact before the main assessment day gets underway.
You will then be gathered in a formal welcome briefing which will guide you through the activities for the day, including timing for tests and interviews, and general housekeeping issues.
The rest of the day may run as follows:
10 a.m. – A series of aptitude tests
11:30 a.m. – E-tray exercise
12:45 a.m. – Break for lunch
1:45 p.m. – Case study group exercise
2:45 p.m. – Interviews
4:15 p.m. – Presentations
5:15 p.m. – Evaluation
5:30 p.m. – End of assessment day
During each activity you will be assessed on a range of key competencies that are required for the opportunity you are applying for.
There can be a number of things that the recruiter will be looking for depending on the industry and the type of job, but the most popular competencies include:
It is important to be professional at an assessment centre. Candidates should behave like the employees of the company they are being assessed by.
You must wear smart business dress throughout: men should wear suits and ties and polish their shoes; women should dress appropriately. If in doubt, dress conservatively.
The first way you can demonstrate effective time management is to arrive punctually. Put your phone on silent so it doesn’t make any noises at inopportune times, particularly during interviews.
There will be lunch and coffee breaks, during which you'll have the opportunity to talk to various staff members, including the current graduate intake and your assessors. Introduce yourself; be polite and confident, look people in the eye and shake hands.
It's a good idea to engage in conversations about the company and the industry. Listen to what others say, and try to ask intelligent and positively framed questions.
You will not be in direct competition with other candidates at an assessment centre. It is normal for large organisations to recruit to a standard. All, several, one or none of your assessment group may be hired.
You need to perform to a very high standard at an assessment centre, but you do not need to challenge, compete or disagree with other candidates. In fact, it may harm your assessors' opinion of you if you do.
Selectors want to see how you react to and get on with other people during your assessments.
Your success at an assessment day will depend a lot on these factors:
Candidates are invited to assessment centres by the firm they have applied to. As guests, attendance is always free, even if perks such as lunch, dinner or hotel rooms are provided.
Most graduate employers will also be willing to cover each candidate's travel expenses, usually up to a maximum of £100.
This can vary: for international applicants, for example, PwC has an allowed expense of up to £100 but if expenses are likely to exceed this amount, applicants are encouraged to contact the recruiter to discuss costs before making any travel arrangements.
A minority of firms (usually small-sized firms with smaller graduate recruitment budgets) will not cover travel expenses.
If you have been invited to attend an assessment centre, you should contact the HR team of the company in question to find out their policy on expenses. It is not rude to do this; graduate employers are fully aware that most students and graduates do not have much money and that travel is expensive.
