The Danger Zone: Top Reasons Candidates Fail
Based on our database of Comstruct interview outcomes, avoid these common traps:
- Running a simple A/B test without controlling for project complexity or client-specific chart of accounts variations
- Focusing solely on volume metrics like total invoices processed without measuring automation rate or touchpoints
- Competing on generic features like simple invoice scanning or standard ACH payments where horizontal players excel
- Measuring only speed improvements while failing to establish a rigorous error monitoring/auditing mechanism

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