Preparation Information

As part of our process it is important to us that we are able to understand who you are and how you will contribute to this customer experience as part of your selection process.

We want to make sure that you will do well in the position that you have applied for and that you will enjoy your new role. The Assessment stage allows you the opportunity to demonstrate what you have to offer, by looking at how you will perform in the core competencies of the role you have applied for.

Research has shown that if people are assessed using systematic and objective exercises then there is a much better chance of selecting the right people to do the job than, if just using an interview. It also ensures that our selection decisions are fair and only made on the basis of core competencies that matter to job performance.

We use both online and in person assessments as well as competency-based interviews. Throughout the process we will provide you with specific information and advise you of what to expect.

How to do your best at your upcoming assessment or interview day:


  • Read the Job Description. Make sure you understand the core competencies we are looking for in the role you have applied for. We tend to base our assessments on the key criteria the role will be expected to deliver, so take the time you need to make sure you understand these. This will give you a better picture of what we are looking to see from you in your assessment.
  • Take a look at our Company Values. Understanding us as a company will help you to know how you might fit in the role you have applied for and what sort of behaviours we are looking for.
  • If you have been provided with Practice Material (not all assessments have practice material). Take the time to go through this and make sure you are comfortable with the type of assessment you are coming in for.

On the day

  • Try to make sure you are well rested on the day of your Assessment. Research has shown that we have greater cognitive function and are able to perform tasks to a higher standard when we have had over seven hours sleep.
  • Stay hydrated. Make use of any breaks you have in the assessment day to grab a drink from our kitchen; our Assessors will show you where this is.
  • Present yourself professionally. Our Assessment Centre is a professional environment and we expect candidates to present themselves accordingly, in terms of attire and personal hygiene e.g. no jeans, hats, or trainers.
  • Bring the correct identification documents. What you need to bring will be clearly detailed in the ‘Evidence Right to Work’ information detailed below.
  • Be punctual. Try your best to be on time to any assessment or interview as it contributes to a positive first impression. However, we to understand that delays happen, so if you are delayed, please get in touch with the HR Resourcing Team as soon as possible.

During the Assessment Centre

  • Try to stay calm. This may be easier said than done, but try to remember that everyone (you, the assessor and the manager) want to see you do your best.
  • Follow the Assessors’ Instructions. The Assessor is there to provide you with a fair environment where you are able to give your best. The instructions they give you will help you to do well in your assessment, so listen closely and ask questions at the appropriate times.

After your Assessment Centre or Interview

  • You will always be entitled to feedback on your performance in an assessment or intervew, either on the day or at a later date via email or telephone (you may contact us after a week to request this if you have not already received it). The feedback will state where you have performed well and areas for improvement, where necessary. It will also give guidance on specific actions you can take to improve your performance on tests. Make sure you take the feedback on board fully as it can help you develop your skills so that you are successful in future assessments and interviews.

What to expect on the day

There will be a Facilitator/Assessor who will look after you throughout the assessment day and will explain everything that will take place. They are the best person to ask any questions and should be able to explain anything you are unsure about. We will provide everything you need to complete your assessment so you will not need to bring anything, unless you are specifically asked to do so.

Overall, just do your best. We look forward to meeting you. Good Luck!
