Europe AI Engineering Interview Guide

Europe does not have one AI interview. A Research Engineer loop at Google DeepMind in London still starts with coding and ML fundamentals; a Booking.com scientist loop is a set of business cases; Bending Spoons in Milan sends a logic test before anyone speaks to you; ML6 in Ghent wants your model deployed to the cloud before the first call. What the markets share is a technical core (attention, LoRA and preference tuning, RAG evaluation, agents with tools, inference cost) and a regulatory layer no other region has: the EU AI Act and GDPR now shape system-design answers.

We collected candidate reports (Glassdoor in its national editions, Taro, PracHub and similar), company job postings and labour-market data between 27 October and 3 November 2026, then audited every question so that all 150 come from 2024 to 2026 sources. Below is a short overview of each market, then the questions. The full guide has a model answer for every question, company loop tables, the tech stack from postings, a roadmap and sources.
