Ericsson Software Engineer Interview Guide

We've seen a consistent pattern at Ericsson: the interviewers want to know whether you can defend the basics you claim on your resume. Multiple candidates reported questions on Java, Python, C++, OOP, data structures, REST APIs, Docker, and Spring Boot, but the tone was rarely about trick questions or deep algorithmic pressure. Even when the process included coding, it tended to stay grounded in practical exercises like implementing FIFO without a queue or solving classic string problems, which tells us Ericsson is screening for solid engineering judgment more than competitive-programming speed.

A recurring theme is that the company cares just as much about how you explain your work as what you built. Our candidates report repeated resume walkthroughs, project deep-dives, and questions about challenges, responsibilities, and why they wanted Ericsson specifically. That makes the non-obvious bar here: can you speak clearly about the tradeoffs behind your own experience? The strongest candidates didn’t just list tools; they connected them to outcomes, design choices, and team collaboration.

We also see a fairly human, low-drama interview style across many experiences, but that doesn’t mean the bar is soft. When Ericsson probes more broadly, it may include networking basics, LLM familiarity, or practical testing scenarios, which can catch people off guard if they’ve only prepared for coding rounds. The candidates who did best were the ones who stayed crisp, grounded, and specific — especially when the conversation shifted from syntax to real-world software thinking.
