How long does the Iliad / Free 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 Iliad / Free?

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 Iliad / Free?

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.

The Danger Zone: Top Reasons Candidates Fail

Based on our database of Iliad / Free interview outcomes, avoid these common traps:

Giving a generic answer about wanting to build products without connecting it to Iliad/Free's mission or the telecom space.
Describing a situation where they simply followed instructions rather than taking initiative.
Designing a plan that's too generic and doesn't address the specific needs of gig workers (e.g., unpredictable data usage, need for reliable connectivity during work hours).
Focusing only on vanity metrics like 'feature adoption rate' without linking it to business outcomes like plan upgrade/downgrade frequency or customer satisfaction.
