Performing well in demanding competency-based interviews requires good preparation. Following these tips will increase your chances of success come assessment day...

What is an assessment centre?

Selection centres assess your suitability for the job through various tasks and activities, allowing employers to test skills that aren't necessarily accessible in a traditional interview. They’re hosted over a one-, two- or three-day period, and you'll usually be joined by six to eight other candidates. It's often the final stage of the selection process for large graduate recruiters.

Assessors - usually a mix of HR consultants and line managers - score your actions against competency frameworks. They discuss all aspects of your performance before reaching a final decision on whether or not to hire you. All, several, one or none of the candidates could be successful.

What happens at an assessment centre?

Graduate assessment centres usually involve a combination of individual and group tasks. Some are designed to mirror your job, while others focus more on the organisation's desired competencies or behavioural characteristics. Potential assessment centre exercises include:

  • case study exercises;
  • group discussions;
  • ice-breaker exercises;
  • interviews;
  • in-tray exercises;
  • presentations;
  • psychometric tests;
  • role play;
  • social events.

How will I be assessed?

Employers don't just assess you against job competencies; they also aim to ensure that you're the right fit. Being scrutinised for such a long time can be challenging, but recruitment assessment centres allow you to compensate for poor performance in one task by excelling in another. Key skills that employers usually look for include:

  • adaptability;
  • analytical thinking;
  • commercial awareness;
  • communication;
  • creativity;
  • decision-making;
  • leadership;
  • negotiation;
  • organisation;
  • persuasion;
  • planning;
  • teamwork;
  • time management.

How do I prepare?

As with interviews, good preparation is vital. Before the day, it's important that you:

  • call the organisation's graduate recruitment team if something is unclear;
  • give yourself time to complete and practise any material that you've been asked to prepare;
  • identify which skills, interests and experiences the employer is looking for by revisiting the job description and any other material that the company has sent you;
  • practise potential exercises with a friend or family member;
  • read the organisation's website, social media profiles and key literature (e.g. business plan, financial reports and corporate social responsibility strategy), ensuring that you're prepared to share your views and ideas;
  • reflect on your first interview, asking the company for feedback, reviewing your performance, and noting any questions or situations that caused you difficulty;
  • research the news, trends, competitors, history and opportunities of the organisation and its job sector;
  • review your CV and application form;
  • visit your university's careers and employability service for further guidance, as many have practice resources, offer one-on-one coaching and host mock assessment centre interviews.

Choose your outfit the night before, get plenty of sleep and avoid alcohol consumption. Plan your journey, aiming to arrive at least ten minutes early. Completing a 'dry run' if possible also combats nerves. On the day, eat a good, healthy breakfast and avoid too much caffeine.

How do I perform well at an assessment centre?

It's important that you:

  • are assertive during all exercises;
  • don't dwell on any mistakes, instead concentrating on performing well in the next task;
  • don't worry about the other candidates, instead focusing on putting your key skills forward;
  • draw others into group discussions;
  • ensure that the assessors can see your working methodology;
  • ensure that you understand the requirements of each task by quickly digesting the brief - revisit this once you understand the overall challenge;
  • join in with discussions, even at 'informal' mealtimes - ask other candidates about university if you're struggling for conversation;
  • maintain a friendly and polite manner with everyone you meet, and remember that you're always being assessed;
  • relax and let your personality shine, as assessors warm to individuality.
