National Grid Assessment Centre – Day 1

To reach the National Grid assessment centre you must complete an online application, a situational judgement test and a preliminary interview.

The National Grid assessment centre is based at the Warwick conference centre and lasts for two days.

The first day will be relaxed and will not feature many exercises. Firstly, you’ll attend a welcome presentation where you will get to know the other candidates and mix with the staff.

  • Remember that you will still be assessed during this time.  You will need to remain professional and courteous at all times, as well as being positive and enthusiastic.

If you’re applying for the graduate scheme, you will also be given 90 minutes to prepare your presentation for the next day.

National Grid Assessment Centre – Day 2

Day two features the following exercises:

  • Presentation
  • Group exercise
  • Interview

National Grid Assessment Centre – Presentation

One of the key elements of the National Grid assessment centre is the candidate presentation. (If you are a graduate candidate, you can prepare your presentation on the first day.)

One of the unusual aspects of this part of the National Grid assessment centre is that the presentation is based around a case study which relates to the role you have applied for. With this in mind, it’s essential that you know the full details of your role.

  • Pro Tip: You can request a copy of the full job description from HR.

During this part of the National Grid assessment centre you will be assessed on your delivery and style. This is an excellent opportunity to show off your skills and personality.

You will need to present for 10 minutes. (Make sure you stick to this time-scale.)

National Grid Assessment Centre: Group Exercise

This exercise is usually dreaded by candidates, but we’re going to teach you how to succeed!

  • You will join a group of candidates and within this group you will need to work together as team.
  • You will be given some information to discuss with your fellow candidates and this information will help you complete the group task successfully.
  • The main thing to remember about group exercises is that the result or conclusion of the task is not important. It’s the process that matters here, not the outcome.

This assessors are watching to see how you interact in a group environment. They are asking themselves the following questions while watching you:

  • Is this candidate a leader?
  • Is this candidate able to influence others without dominating them?
  • Is this candidate listening to others or just waiting for an opening to speak?
  • Is this candidate contributing to the discussion? (It’s amazing how many people sit silently during group exercises.)

National Grid Assessment Centre: Interview

This interview will be competency-based. This means that the assessor will be looking for you to demonstrate whether you are a good fit for the company.

The National Grid’s company-wide values and competencies are listed below:

  • Commercial awareness
  • Teamwork and relationship building
  • Planning and organising
  • Problem solving and decision making
  • Communication and customer service

You must show that you possess these qualities in your interview.

The question is how?

The best way to do this, is to look at each competency and think about when you have demonstrated each of them.

If you do only one piece of prep for your National Grid assessment centre this should be it.

  • Write down a list of examples for each of the above competencies. Pick carefully. Make each example detailed and memorable. Embellish the story as much as you can get away with.
  • Memorize the examples.

You will return to this list of examples again and again during your National Grid assessment centre.

The all-conquering importance of practice

If you’re serious about succeeding at your National Grid assessment centre you must take the time to practice each of the assessment exercises you will face at the event.

We can give you great tips and advice, sure, but it’s down to you to put the preparation hours in.

  • If there’s one thing we’ve learned from long experience it’s that preparation is the difference between success and failure. Successful candidates are consistently better-prepared than unsuccessful ones.

Research the company & market

Make sure you are up to date with what is happening for National Grid presently and what they have planned for the future.

  • What do their operations look like?
  • What’s their company ethos?
  • Who are their competitors? What are the threats to their business?
  • What’s happening in the next 1-3 years? What’s the company vision?
  • What big projects are underway?
  • Who are the key stakeholders?

If you had to give an executive summary of the company’s commercial performance, could you? (Revenue, profits, level of debt?)

Pro Tip: Most candidates won’t know this. If you spend an hour looking through their annual report you can get all this information and look like the best prepared, smartest and most hungry candidate of all.

You can access National Grid’s annual reports (a treasure trove for a job applicant) here.
