The Graphcore DNA (TL;DR)

The technical deep-dive rounds at Graphcore heavily assess a candidate's depth in their domain, specifically around novel approaches to AI compute. Interviewers, often senior engineers, probe for original thinking and how one would contribute to the evolution of IPU technology, reflecting the vision of Nigel Toon and Simon Knowles.

The Graphcore Interview Loop

Your onsite loop will typically consist of 5 rounds.

  1. 1

    Round 1

    Recruiter Screen
    Motivation, customer-facing experience, fit with the segment (SMB / Mid-market / Enterprise).
  2. 2

    Round 2

    Customer Story
    Walking through how you saved an at-risk account, drove adoption, or expanded a customer.
  3. 3

    Round 3

    Renewal & Expansion
    QBR roleplay, identifying expansion signals, navigating churn risk, multi-stakeholder alignment.
  4. 4

    Round 4

    QBR Roleplay
    Live mock QBR - presenting health metrics, ROI evidence, and renewal/expansion narrative to a customer panel.
  5. 5

    Round 5

    Behavioral / Leadership
    Past evidence of ownership, influence, resolving conflict.

The Danger Zone: Top Reasons Candidates Fail

Based on our database of Graphcore interview outcomes, avoid these common traps:

  • Failing to connect technical performance gains to tangible business benefits (e.g., cost savings, faster time-to-market).
  • Not learning from the experience or applying lessons to future interactions.
  • Focusing only on logical arguments without considering the other person's viewpoint or emotions.
  • Asking generic questions that don't probe for new use cases or challenges.

Test Yourself: Real Graphcore Questions

Three real prompts pulled from our database.

Type · Ownership & Initiative

STAR
When working with customers deploying large-scale AI models on IPU clusters, you may encounter unique hardware-software bottlenecks that are not yet documented in our knowledge base. Tell me about a time you identified a recurring performance bottleneck in a customer environment and proactively worked with our internal engineering or silicon architecture teams to develop a new diagnostic process or workflow to solve it.

Type · Account Expansion

Tell me about a time you successfully expanded a customer account. What signals indicated an opportunity for expansion, and how did you leverage your relationship to achieve it?

Type · Conflict Resolution

STAR
Tell me about a time you had a significant disagreement with a customer regarding the value or performance of Graphcore's technology. How did you handle the conflict, and what was the resolution?

Frequently asked questions

How long does the Graphcore interview process take?

Most candidates spend between 4 and 8 weeks from recruiter screen to offer. The onsite loop itself runs in a single day or is split across two half-days, with debrief and offer typically within 5 business days after.

How should I prepare specifically for Graphcore?

Focus on three things: (1) the company DNA shown above - what they actually grade for, (2) the rounds in your loop, especially the round most candidates underestimate, and (3) drilling on the question types in this guide using a structured framework like CIRCLES or STAR.

Does this apply to engineering or design roles at Graphcore?

The DNA stays the same - what changes is the round mix. SWE candidates face coding screens instead of Product Sense; designers face portfolio reviews and design exercises. The "what they value" and behavioral signals carry across all functions.
