Once you know what you’re looking for, you can head to the website to begin your search and apply for the role(s) that best suit you.

If there’s nothing listed that looks appropriate, it’s worth signing up for job alerts so you’re notified when the right role comes along.

National Grid Online Application

The online application is the first proper step in the National Grid recruitment process, and you'll need to set up an account before proceeding.

The application form is divided into three distinctive sections. The first requires basic information about you and your academic history.

The second part is a series of questions designed to assess your motivation and skill level. Questions could include: Why do you want to work for National Grid? Or, Why are you interested in this particular role?

The third and final part is a situational judgment test which will present you with a hypothetical workplace scenario, and four possible responses for you to choose between. Remember to review National Grid’s values and objectives before considering your answers.

The application form may take around an hour to complete, but you can save and return to it.

Before submitting any application, it’s always prudent to check it thoroughly and ensure you’re happy all the information you've given is accurate and that you’ve made no spelling or grammatical errors.

National Grid Video Interview

If your application is successful, you’ll be invited to take part in a video interview.

The interview is designed to assess your capability for the role. It’s usually comprised of three competency-based questions that will probe your personal work style and your personality. This allows the recruiters and hiring managers at National Grid to see how you might fare as part of the team.

You can record your responses to the question in a time and place that suits you. Try and find an area free from noise and distraction. Think about how you present yourself on camera, and ensure your backdrop is appropriate for the task at hand.

National Grid Game Based Assessments

Those that are successful in the video interview portion of the recruitment process will be invited to take part in the game-based assessments.

These short games will test your cognitive, social and emotional traits, and require you to think on your feet.

To complete this section, you’ll need to have access to a device that can connect to the internet.

National Grid Assessment Center

If you score highly on the game-based assessments you’ll be invited to the final portion of the process — the assessment center.

Depending on the role or scheme you’re applying for, this could be up to two days in length and could include anything and everything from a pre-prepared presentation to an interview with someone from the senior management team.

As well as testing your skills and knowledge, the day is a chance for you to meet other applicants and get to know a few of the people working at National Grid. You’ll be observed throughout the day(s) so it’s important to bring enthusiasm and curiosity, while also ensuring you're respectful when others talk.

Although this will vary depending on the role, most National Grid assessment centers start with candidates sharing their pre-prepared presentation and taking questions for up to 90 minutes. The presentation subject tends to be a case study that’s relevant to the role you’re hoping to acquire.

You’ll also take part in a group exercise where you’ll be assessed on your teamwork, cooperation, leadership and listening skills.

There will also be a face-to-face interview. The questions in this interview are competency-based, and you’ll need to demonstrate skills including communication, organization, customer service and market knowledge.

Preparing for the assessment center is really important as by this stage, you have a very real chance of getting the job.
