Overview

Interviewing for Mechanical Engineer at Graphcore

Interviewing for a Mechanical Engineer position at Graphcore is a distinct experience from applying to the same role elsewhere. Graphcore, as a high-growth organisation with 400+ employees, has built a structured hiring process that reflects both the demands of the Mechanical Engineer role and the company's own values and culture. The process is designed to assess not just whether you can do the job technically, but whether you'll thrive in Graphcore's specific working environment.

For Mechanical Engineers specifically, Graphcore tends to emphasise practical problem-solving and technical depth alongside cultural fit. You should expect a process that tests your ability to work with tools like CAD design and 3D modelling, Finite element analysis, Thermodynamics and heat transfer in realistic scenarios, not just abstract theory. The interviewers are typically people you'd be working with directly, so the conversation goes both ways — they're evaluating you, but you're also getting a genuine sense of the team and day-to-day work.

Understanding what Graphcore values — and how that translates into their interview expectations for a Mechanical Engineer — gives you a significant advantage. This guide breaks down the full process, the specific questions you're likely to face, and how to prepare effectively.

Process

How Graphcore interviews Mechanical Engineers

Graphcore's interview process for Mechanical Engineer roles typically runs 2-4 weeks and involves 5 distinct stages. The process begins with application screening and progresses through increasingly focused assessments. Each stage is designed to evaluate different aspects of your suitability — from baseline qualifications through to cultural alignment and role-specific capability.

For Mechanical Engineer candidates specifically, expect the technical stages to focus on your hands-on ability with CAD design and 3D modelling, Finite element analysis, Thermodynamics and heat transfer, Material science and selection. Graphcore typically includes a practical assessment — this could be a coding challenge, a system design discussion, or a technical case study depending on the seniority level. The behavioural stages will probe your collaboration style and how you handle ambiguity, since Mechanical Engineers at Graphcore work across teams regularly.

Preparation

How to prepare for your Graphcore Mechanical Engineer interview

Preparing for a Mechanical Engineer interview at Graphcore requires a dual focus: you need to master the role-specific technical requirements and understand how Graphcore operates as an organisation. Start by thoroughly reviewing the job description and mapping your experience against every requirement. For each skill or qualification listed, prepare a specific example from your career that demonstrates competence — ideally with quantifiable outcomes.

On the technical side, refresh your knowledge of CAD design and 3D modelling, Finite element analysis, Thermodynamics and heat transfer, Material science and selection. Graphcore will likely test these in practical scenarios, so practice working through problems out loud. Review Graphcore's tech stack or engineering blog if publicly available — understanding their technical choices helps you frame your answers in their context rather than speaking generically.

Research Graphcore beyond their website: read recent news, check their Glassdoor reviews (their rating is 4.1/5 (based on recent reviews)), and look at what current employees say about working there. Understanding their culture helps you frame your answers authentically and ask informed questions — interviewers notice when a candidate has done their homework versus when they're winging it.
