The Ionity DNA (TL;DR)
Ionity's interview loop heavily emphasizes candidates' ability to navigate complex, real-world scenarios related to EV charging infrastructure.

The Danger Zone: Top Reasons Candidates Fail
Based on our database of Ionity interview outcomes, avoid these common traps:
- Ignoring the capital expenditure and operational costs associated with battery storage.
- Suggesting a split budget that results in neither project achieving full ROI
- Focusing only on one aspect of differentiation (e.g., just price) without a holistic view.
- Underestimating the importance of ancillary services or amenities at charging locations.

Frequently asked questions
How long does the Ionity 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 Ionity?
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 Ionity?
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.
