Interview Process Overview
The interview process for a UX/UI Designer at National Grid is highly structured and relies heavily on automated, asynchronous screening platforms in the early stages. Unlike standard design interviews that might start with a casual recruiter call, you should expect to face a formalized online assessment early on. This initial stage is typically conducted via a platform like HireVue and does not involve speaking to a live person.
During this asynchronous phase, you will face a series of timed cognitive tests, which often include sequence and puzzle challenges designed to test your analytical thinking. Following the tests, you will be prompted with behavioral and scenario-based questions. You will need to record your answers on video, usually with a strict time limit of 1.5 to 2 minutes per response, though you are typically given one opportunity to retry your recording if you stumble.
If you successfully pass the automated screening, you will progress to live interviews with the design and product teams. These later stages typically involve deeper portfolio reviews, behavioral deep-dives, and discussions around your specific UX/UI methodologies. Keep in mind that scheduling between these stages can sometimes require patience, as coordination across internal teams may introduce delays.
This visual timeline outlines the progression from your initial asynchronous HireVue assessment through to the final live portfolio and behavioral rounds. Use this to structure your preparation, focusing first on cognitive tests and timed video responses before shifting your energy to deep portfolio presentations. Note that while the automated stages are standardized, the timeline for live interviews may vary depending on the specific team and location.
