The Danger Zone: Top Reasons Candidates Fail
Based on our database of 1KOMMA5° interview outcomes, avoid these common traps:
- Giving a generic answer about 'sustainability' without linking it to 1KOMMA5°'s specific approach.
- Failing to differentiate between simple hardware sales and complex integrated system sales
- Not tailoring the pitch to the homeowner's stated motivations (carbon footprint, cost savings).
- Treating all leads with the same level of urgency regardless of project complexity

Frequently asked questions
How long does the 1KOMMA5° 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 1KOMMA5°?
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 1KOMMA5°?
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.
