How to Pass the Dwelly Software Engineer Interview in 2026

The Dwelly DNA (TL;DR)

Focus on Customers, a core principle championed by Ilya Drozdov Co, anchors the evaluation process. Interviewers look for candidates who can dissect the friction in Dwelly Renting and propose structural product improvements rather than generic operational fixes.

The Danger Zone: Top Reasons Candidates Fail

Based on our database of Dwelly interview outcomes, avoid these common traps:

  • Failing to articulate how the decision impacted the end-user experience for tenants or landlords.
  • Failing to handle ties in popularity
  • Hardcoding tenant IDs in every query without index support
  • Focusing on the personal friction rather than the technical trade-offs between speed and scalability.
