The Danger Zone: Top Reasons Candidates Fail

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

Ignoring the impact of the decision on other teams within the Adevinta ecosystem
Inefficient character-by-character comparison across all strings for each prefix.
Giving a generic answer not specific to Adevinta or the online classifieds industry.
Ignoring data storage and retrieval mechanisms for user history and product data.

Test Yourself: Real Adevinta Questions

Three real prompts pulled from our database.

Type · Algorithmic

You are given a list of user search queries for an e-commerce platform. Write a function to find the longest common prefix among all the search queries. If there is no common prefix, return an empty string.

Type · Technical Conflict

Adevinta operates a distributed architecture where different teams own microservices that interact heavily. Describe a time when you and another engineering team had competing requirements for a shared API or data schema. How did you navigate the trade-offs between local team velocity and global platform consistency?

Type · Ownership

Marketplace platforms often face technical debt when scaling across different regional brands like Le Bon Coin or Marktplaats. Tell me about a time you identified a systemic issue in a legacy codebase that was impacting user experience and chose to lead the refactoring effort, even when it required balancing that work against high-priority product roadmap features.
