Ground every answer in facts on this page and the original listing. We never invent Glassdoor-style reviews or salaries that are not in our data.
Be ready to discuss Java concurrency, API design, data modeling, testing, and how you diagnose production issues. Walk through a past backend system you owned: trade-offs, failure modes, and what you would change. For an Azure-leaning staff title, expect questions on cloud service choices and operational concerns.
Strong fit if you already ship production Java services, can own backend design decisions, and prefer on-site/hybrid work in Berlin at Atolls. Less fit if you want remote-first work or primarily frontend/product roles.
