How long does the LEGO Group 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 LEGO Group?

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 LEGO Group?

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.

How to Pass the LEGO Group Software Engineer Interview in 2026

The LEGO Group DNA (TL;DR)

The 'Learning Through Play' philosophy at LEGO Group deeply influences their hiring, assessing candidates on their ability to innovate within structured systems and foster environments where creativity flourishes, much like building with LEGO bricks. They look for individuals who can articulate how their work contributes to a larger, playful vision, often through scenario-based questions related to product development in Billund, Denmark.
