Interview Guides
Everything we know about interviewing at National Grid: the process stage by stage, what each round tests, compensation by level, and reports from candidates who interviewed.
What the process looks like, and what National Grid is really testing for.
National Grid uses a mix of screening, recorded digital assessments, and live interviews that heavily emphasize data analysis, role execution skills, and structured communication. Across the extracted topic data, Data Analysis is the most prominent topic, and Project Management appears as a core, highest prominence area.
What you actually get tested on is the combination of Data Analysis plus case and scenario work, communication, and behavioral and leadership assessment. The topic list is dominated by Data Engineering, Pandas, Power BI, Business Analysis, Product Management (core role), and QA Engineering, and it also includes Behavioral Interviewing, Problem Solving, and Case Study Analysis.
The loop you experience can start with an initial screening plus recruiter or HR discussion, then move into digital assessments like pre-recorded video and automated or game-style cognitive checks. Some paths include group case studies and live panel interviews, and others appear to end early after digital screening, with no offers reported in the aggregated candidate reports.
You should treat the digital stages as a real gate, not a formality. Multiple candidate reports describe HireVue style recorded interviews and game or cognitive checks where candidates were disqualified early or did not progress, even when later human interviews were described as manageable.
4 stages, based on 476 candidate reports.
You start with an initial screening that assesses your background and fit for the role. Some roles also include an initial screening call with a recruiter or HR focused on your background, motivations, and salary expectations.
You may complete a pre-recorded video interview with behavioral questions and cognitive assessments, plus automated or game-style checks. Candidate reports describe structured prompts, timing constraints, and additional logic or numeracy style tasks, with some candidates not progressing after this stage.
Some roles include case studies and group case study exercises. You work through scenario-based material, and assessors observe teamwork and problem solving, with later discussion used to evaluate analytical thinking.
You may interview in live panel sessions with hiring managers and senior engineers, focusing on behavioral deep-dives and role-aligned questioning. Some processes include a final discussion or final interviews to finalize assessment and cover alignment with company values, with additional deeper screening calls involving directors or team members reported in some cases.
