I applied online. I interviewed at National Grid (Warwick, West Midlands, England) in Feb 2022
Interview
I found the job description in LinkedIn, which took me to the National Grid website, there I applied. The whole process took about 30min. The next day I have received an reply back that I do meet the minimum criteria for the role I have applied, which I guess have been the course I am studying. I had been given a link to HireVue, where I had to answer 6 questions and play 2 games, throughout the whole time my camera was enabled. Each question had about 30 seconds prep time and 3mins to answer. You could re-record up to 4 times. The games were 1) matching the patterns, 2) numeracy. They were really fun to do.

Interview
Day long assessment centre following an existing formula that they use. The whole process felt redundant since the staff were mollycoddling one of the interviewees whose parent worked at the company.

I applied online. The process took 4 months. I interviewed at National Grid in Mar 2021
Interview
This is a very elaborate description just so you are prepared. The entire process took several months, I applied in November; but I loved that they kept sending those emails that showed that you were still in the running for the position.
First stage was the Situational Judgement Test, for which the results and analysis came back pretty quickly.
I think next stage was the video interview, there were pre recorded questions about experience working in a team and working alone.
Then third stage was review from the hiring manager. I did not get any call and I was not involved in this review in any way. I was just told I had pass the SJT and video interview, and now I am in the review stage; so it's just one of those things you have to wait out with fingers crossed.
Then I was told I had passed and I had to select a date for the virtual assessment. Also, they give you a detailed email and pdf files on what to expect from the virtual assessment.
I did the assessment towards the end of March, which consisted of a networking session, presentation and interviewing session.
For networking, I was in a group with 4 other candidates, 2 current graduates in the company and 2 employees. Everybody does an intro and then the floor is open for questions.
For the presentation, I was given a document with details of a project proposal for three transmission route plans. The challenge is actually in the volume of the document, if you think you have too much time, you might get swamped up in information because that brief was not soo brief (about 9 pages long or so). Each of the route had pros and cons, and you are meant to weigh the pros and cons and decide which route was best in terms of cost, customer satisfaction and all. Then propose a communication strategy.
Then the interview were all questions from the competency category file given before the interview..cant remember them all but I remember thinking I did really badly in that session but apparently I was wrong.
This interview took 3hrs, so be prepared for that.. That's as elaborate as I can get, and as I wished someone had been for mine because I was not prepared at all.
Finally, my interviewer was a very people-friendly person, he was so attentive, and he kept making funny remarks from his own experience. The second guy was stern but also attentive. That was wholesome for me.
After the interview, within the next week, I was called to confirm my verbal offer.
